AB  - This paper aims to develop an amperometric, non-enzymatic sensor for detecting and quantifying UA as an alert signal induced by allergens with protease activity in human cell lines (HEK293 and HeLa). Uric acid (UA) has been classified as a damage-associated molecular pattern (DAMP) molecule that serves a physiological purpose inside the cell, while outside the cell it can be an indicator of cell damage. Cell damage or stress can be caused by different health problems or by environmental irritants, such as allergens. We can act and prevent the events that generate stress by determining the extent to which cells are under stress. Amperometric calibration measurements were performed with a carbon paste electrode modified with La(OH)3@MWCNT, at the potential of 0.3 V. The calibration curve was constructed in a linear operating range from 0.67 μM to 121 μM UA. The proposed sensor displayed good reproducibility with an RSD of 3.65% calculated for five subsequent measurements, and a low detection limit of 64.28 nM, determined using the 3 S/m method. Interference studies and the real sample analysis of allergen-treated cell lines proved that the proposed sensing platform possesses excellent sensitivity, reproducibility, and stability. Therefore, it can potentially be used to evaluate stress factors in medical research and clinical practice.

AB  - The emerging threat of bacterial resistance to antibiotics prompts the urgent search for biomaterials for the treatment of infectious disease. Here we report on the synthesis and characterization of a multiphasic nanocomposite comprising magnetic iron oxide and silver nanoparticles. The method of synthesis involved the combustion of a metalorganic complex and reduction of the silver ions that were exchanged and/or adsorbed on the surface of iron oxide. Different physical and chemical treatments coupled to the reduction process, including ultrasound and Lugol's iodine solution, respectively, homogenized the distribution of the silver nanoparticles on the iron oxide phase. Remarkably, using ascorbic acid as a reductant enhanced the magnetic properties of the material as a result of the reduction of the magnetic matrix alongside the silver cations. The treatment with ultrasound detached large amounts of silver from the iron oxide phase and resulted in the lowest amount of silver incorporated in the nanocomposite. Despite that, this treatment led to the highest antibacterial activity against both Gram-positive and Gram-negative strains, indicating that the homogeneity of the distribution of silver on the iron oxide matrix is a more important determinant of the antibacterial performance than the amount of silver incorporated in the material. At the same time, the treatment with Lugol's iodine equally increased the distribution homogeneity, but induced excessive ion exchange and crystal lattice substitutions, thereby adversely affecting the antibacterial performance. This has indicated that the mode of binding silver to iron oxide can compensate for the positive effects of homogeneous distribution with respect to the antibacterial performance.

AB  - There is a significant interest in understanding coordination and photo-chemistry of tetracycline antibiotics, primarily in relation to the development of advanced oxidation processes for degradation of these pollutants in water processing. Herein we analyzed the pH-dependence of interactions of tetracycline with ferric iron and photosensitivity of tetracycline to UV-A and UV-B, using a set of methods – UV–vis, Raman and electron paramagnetic resonance spectroscopy, MS spectrometry, HPLC, and cyclic voltammetry. Tetracycline and Fe3+ mainly bind through amide and OH groups in tricarbonylamide moiety to form a stable complex with 1:1 stoichiometry at pH ≤ 5. The interaction is reversible and tetracycline is released from the complex with pH increase. Tetracycline in the complex is stabilized and less susceptible than free tetracycline to oxidation by hydroxyl radical that is produced by UV-induced photolysis of Fe3+–OH- complexes. Redox properties of tetracycline were altered with increasing pH and it showed increased susceptibility to UV-induced degradation. In close, the system composed of tetracycline and ferric iron shows coordination and photo-redox chemistry that is dependent of pH in relation to the solubility of Fe3+ species and protonation of tetracycline. The development and optimization of advanced oxidation processes should take into account that iron may bind and stabilize pollutants and that the redox landscape of water changes drastically with pH.

AB  - Nickel acetate tetrahydrate (NAT) sample series were used to modify screen-printed carbon electrodes (SPCE). The samples were hybrid Ni/NiO nanocomposites, where the NiO phase increased with an applied treatment temperature. Results of electrochemical measurements pointed that the Ni/NiO550/SPCE-modified electrode had the best analytical performance toward the detection of riboflavin (RF). The Ni/NiO550/SPCE-based sensor showed linear response with RF in the concentration range of 0.5–75 μM and 0.15 μM LOD in BRBS. Sensor offered fast response time, good repeatability, and selectivity with an RSD of 1.4 %. Our results show that the Ni:NiO nanocomposite ratio strongly influenced the electroanalytical performance of SPCE.

Results of electrochemical measurements pointed that the Ni/NiO550/SPCE-modified electrode had the best analytical performance toward the detection of riboflavin (RF). The Ni/NiO550/SPCE-based sensor showed linear response with RF in the concentration range of 0.5–75 μM and 0.15 μM LOD in BRBS. Sensor offered fast response time, good repeatability, and selectivity with an RSD of 1.4 %. Our results show that the Ni:NiO nanocomposite ratio strongly influenced the electroanalytical performance of SPCE.",

AB  - Two new Schiff base cobalt(III) ([Co(LH)Cl2], 1) and nickel(II) ([Ni(LH)ClO4], 2) complexes with a diimine-dioxime ligand, (4,9-diaza-3,10-diethyl-3,9-dodecadiene-2,11-dione bis oxime (LH2)), were synthesized and characterized. The compounds were obtained in MeOH from corresponding metal salts and LH2 in molar ratio 1:1 and further characterized by mass spectrometry, IR spectroscopy, electrochemistry, and elemental analysis. Previously reported copper(II) analog, ([Cu2(LH)2]·(ClO4)2, 3) was joined to 1 and 2, and the three metal analogs, 1-3, were further investigated in terms of their electrochemical behavior. The binding studies of the complexes with deoxyribonucleic acid (DNA) and human serum albumin (HSA) were carried out using both spectrophotometric and electrochemical methods. All three complexes exhibit binding affinity towards the DNA chain through intercalative interaction. The binding reaction with HSA showed for 1 and 3 complexes decrease in the peak current obtained in the case of complexes before the addition of HSA, while resulted compound obtained from Ni complex – HSA possesses the same electroactivity as starting complex. Furthermore, the cytotoxicity of LH2 as well as its metal complexes, and cisplatin were evaluated on CT-26 mouse colon carcinoma and human LS174T cancer cell lines employing MTT assay. The copper(II) complex exhibited very promising anticancer activity compared with cisplatin.

AB  - Compounds used in the fashion industry effect the water bodies in the vicinity of textile factories, resulting in the visible coloration of surface water. Fe-doped graphite-based in house prepared electrodes were used in the Fenton--like degradation of Reactive Blue 52 (RB52). The electrodes consisting of high-density graphite in three granulation sizes and three levels of Fe content were characterized using scanning electron microscopy (SEM). The amount of Fe in the electrodes and H2O2 concentration in syn­thetic textile wastewater were optimized. Additionally, the size of graphite grains was varied to inves­tigate whether it effects the degradation rate. Under only 10 min of electro-Fen­ton degradation, a system with 10 mmol dm-3 of H2O2 and an electrode made of 7 % of Fe and 70 µm of granulation size of graphite, degraded over 75 % of RB52, and over 99 % after 40 min of treatment. The obtained results indicate that the proposed approach could be beneficial in the field of novel materials for environmental applic­ation and that in house prepared carbon could be an excellent replacement for commercially available supports.

AB  - There is a significant interest in understanding coordination and photo-chemistry of tetracycline antibiotics, primarily in relation to the development of advanced oxidation processes for degradation of these pollutants in water processing. Herein we analyzed the pH-dependence of interactions of tetracycline with ferric iron and photosensitivity of tetracycline to UV-A and UV-B, using a set of methods – UV–vis, Raman and electron paramagnetic resonance spectroscopy, MS spectrometry, HPLC, and cyclic voltammetry. Tetracycline and Fe3+ mainly bind through amide and OH groups in tricarbonylamide moiety to form a stable complex with 1:1 stoichiometry at pH ≤ 5. The interaction is reversible and tetracycline is released from the complex with pH increase. Tetracycline in the complex is stabilized and less susceptible than free tetracycline to oxidation by hydroxyl radical that is produced by UV-induced photolysis of Fe3+–OH- complexes. Redox properties of tetracycline were altered with increasing pH and it showed increased susceptibility to UV-induced degradation. In close, the system composed of tetracycline and ferric iron shows coordination and photo-redox chemistry that is dependent of pH in relation to the solubility of Fe3+ species and protonation of tetracycline. The development and optimization of advanced oxidation processes should take into account that iron may bind and stabilize pollutants and that the redox landscape of water changes drastically with pH.

AB  - The textile industry is one of the major pollutants of waterbodies with effluents high in biochemical and chemical oxygen demand values, high values of total dissolved solids, total suspended solids, and low dissolved oxygen values along with strong color. The existence of a successful method for its decontamination would be beneficial. In this work, we synthesized sponge-like europium oxide (Eu2O3) using a template-directed route from carbon hollow spheres, obtained from glucose as a carbon source. The material synthesis method was done in an aqueous environment, without using any organic solvents. Electrochemical properties of the synthesized material were investigated using cyclic voltammetry and electrical impedance spectroscopy, while morphological characterization was done using scanning electron microscopy and X-ray powder diffraction analysis. Eu2O3 were successfully immobilized at the surface of a screen-printed carbon electrode (Eu2O3/SPCE) using the drop-casting method. Finally, the prepared electrodes were tested toward the removal of Reactive Blue 52 (RB52) using electrochemical advanced oxidation processes (EAOPs). Important parameters, that is, the supporting electrolyte, its concentration, pH value, and the applied voltage, were optimized for RB52 degradation. The rate of removal was monitored spectrophotometrically and by high-performance liquid chromatography with a diode array detector (HPLC-DAD). It was found that the proposed approach reaches complete decolorization of the RB52 solution after a 60-min treatment, at pH 5.6 of KCl supporting electrolyte at a concentration of 0.05 M. Under optimal parameters, after 3 h of treatment, total organic carbon (TOC) was lowered by ~40%. The obtained results indicate that the proposed method may find potential application in EAOPs, considering electrode stability, durability, and efficiency and simplicity of the method.

AB  - Pure and Cr-doped hematite (α-(Fe1-xCrx)2O3, x = 0, 0.026, 0.039, 0.085 or 0.135) nanorods were prepared by a simple co-precipitation and calcination method. Influence of different levels of Cr doping on the change of properties of long and thin pure hematite nanorods was investigated. Cr3+-for-Fe3+ substitution in the crystal structure of hematite was proved by measuring a gradual contraction of the unit cell and a gradual decrease of the hyperfine magnetic field by increasing the Cr molar fraction. Cr doping induced an increase in the width and thickness of hematite nanorods, as well as a decrease in the overall surface area. Low temperature 57Fe Mössbauer spectroscopy showed that the Morin transition in hematite was suppressed by Cr doping to temperatures below 80 K. Magnetic measurements confirmed the suppression of the Morin transition in Cr-doped hematite down to 5 K. Infrared spectra of Cr-doped hematite samples showed shifts of IR bands by Cr3+-for-Fe3+ substitution. Optical properties of α-Fe2O3 nanorods changed significantly by Cr doping – the absorption edge was shifted to higher wavelengths, accompanied by a greater absorption in the visible range and narrowed direct and indirect optical band gaps. The improved visible light photocatalytic activity of hematite nanorods in the heterogeneous photo-Fenton process by moderate Cr doping was measured, which can be attributed to the modifications in electronic structure and optical properties.

AB  - Based on graphene nanoplatelets capability to build block composites, as well as well-known electrochemical characteristic of the manganese oxide materials, in the present research, a nanocomposite, formed from graphene nanoplatelets (GNP) and manganese(IV)-oxide (MnO2) nanoparticles, has been proposed as a novel and convenient support for enzyme immobilization. Performance of screen printed carbon electrodes (SPCEs) was significantly improved after their modification with GNP@MnO2 (SPCE/GNP@MnO2). The polyphenolic index biosensor was prepared by applying the drop coating technique using laccase and Nafion®. Developed biosensor shows a fast and reliable amperometric response toward caffeic acid, as a model compound, at operating potential of +0.40 V (vs Ag/AgCl), with a wide linear range and detection limit of 1.9 μmol l−1. Developed procedure was successfully applied for the determination of polyphenolic indexes in wine samples. Recovery tests indicate excellent accuracy and precision of the method, concluding that the biosensor can offer a fast, accurate, reliable and precise determination of the polyphenolic index. More importantly, our results suggest a great potential for the application in real samples.

Recovery tests indicate excellent accuracy and precision of the method, concluding that the biosensor can offer a fast, accurate, reliable and precise determination of the polyphenolic index. More importantly, our results suggest a great potential for the application in real samples.",

AB  - L-DOPA (L-3,4-dihydroxyphenylalanine), the precursor of dopamine, is widely used in the treatment of Parkinson’s disease, thus determining and monitoring the concentration of L-DOPA is of utmost importance for both medical and scientific purposes. Although many analytical approaches, designed for drug detection and quantification, already exist, there is a constant need for modification of old and tailoring of new, faster, and selective methods. Redox active chemical species, such as L-DOPA, can be measured directly by electrochemical means, whereas electrochemical sensors combine sensitivity and selectivity within a small analytical device. This work demonstrates the development of such electrochemical sensor, based on carboxylated single-wall carbon nanotubes (SWCNT-COOH) decorated with SiO2 coated-Nd2O3 nanoparticles, and further application for the detection of L-DOPA. Developed SWCNT-COOH@Nd2O3-SiO2 sensor shows linear response in the range from 2 µmol L−1 to 52 µmol L−1 analyte concentration, and beside the low detection limit, it is characterized by a fast response time, as well as good life-time, reproducibility and repeatability.

AB  - The homemade, porous carbon material, thermolysis prepared from Novolac phenol-formaldehyde resin, in situ modified with Co3O4 nanoparticles and mixed with single-wall carbon nanotubes, was used in selective sensing of prominent antioxidant α-lipoic acid (LA). XRD, SEM and EIS measurements were used for characterization of material composition, structure, morphology and improved conductivity. The quantification of LA at TPCo3O4&SWCNTCPE was done by a square-wave voltammetric technique in BR buffer solution at pH 6. The linear working range was recorded from 2 to 100 μM of LA and the proposed electrode material was successfully applied in the determination of LA in dietary supplements.

AB  - Honokiol is neolignan present in the magnolia bark. It displays versatile pharmacological properties—neuroprotective and anxiolytic effect, anti-cancer activity and antimicrobial effect being the most important. This paper aims to develop a voltammetric non-enzymatic biosensor for honokiol detection, quantification and monitoring in drugs and cosmetic products. The materials used in this study were synthesized and characterized by HR-XRPD, SEM, ATR-FTIR and electrochemical methods. Bi2O3, being a p-type semiconductor, was used as an electrode material. Both its semiconductivity and electrocatalytic properties result from lattice structure defects, which differ on the surface and in the bulk of the bismuth oxide crystal, and therefore are crystal size dependent. The influence of the particle size of Bi2O3 on its electrocatalytic properties was studied, and it was confirmed that Bi2O3 nanoparticles have better overall conductive/resistive and catalytic characteristics than microribbons and that the optimal electrode modification for sensing application was obtained by Bi2O3@SWCNT composite material preparation. Here, we established a sensitive electrochemical sensing platform for honokiol detection based on CP electrode modified with bismuth oxide nanoparticles and SWCNT with the 0.17 μM limit of detection, and linear operating range from 0.1 to 50 μM. The effect of potential interferents on honokiol detection was explored. Obtained results in the interference tests and the real sample analysis suggest that the developed approach is selective, accurate and reproducible. Due to the low detection limit and a wide working range, the proposed sensing platform opens great opportunities for further construction of sensors for honokiol detection and monitoring in the pharmaceutical industry and medicinal chemistry.

AB  - This work presents advanced electrochemical platform based on screen printed diamond electrode (SPDE) system for the single drop “point-of-care” testing. Proposed approach was applied for the quantification of doxorubicin hydrochloride (DOX) in biological fluids and pharmaceutical product. Using a single drop (~30 μL) of the tested solution at the electrode surface, DOX showed high electroactivity over a wide range of pHs. In these conditions, single oval shaped, well-defined and pH dependent oxidation peak was observed in the potential range from 0.5 V to 1.3 V. In the reverse scan, two cathodic peaks, were noted – around 0.3 V and – 0.5 V. Similarly, first reduction peak was pH dependent, while second one was independent in the studied range. Experimental conditions for DOX quantification were optimized and natures of the electrode reactions were investigated. Working linear range obtained for DOX detection was from 0.1 to 2.5 μM. Diffusion controlled electrode reaction reveal long life time of the proposed electrode as well high potential for practical application. Developed procedure was successfully applied for the DOX analysis in biological fluids – urine and pharmaceutical formulation. Obtained results clearly indicated that given procedure can be easily implemented for pharmaceutical control and medical analysis, in both, laboratory and field conditions.

AB  - BACKGROUND: Pectin is a complex polysaccharide, present in fresh and processed food as an additive, which also serves as an important source of fiber. In this work, the aim was to investigate in-vitro application of apple pectin as a possible antimicrobial, antioxidant and prebiotic agent for growth of bacteria selected from human milk and infant feces, as well as standard strains Lactobacillus rhamnosus and Bifidobacterium bifidum.
METHODS : All the bacteria isolated from the milk of mothers of preterm and term-born infants, bacteria from infant feces and standard strains were tested for fermentation of apple pectin as the main carbohydrate in selective broth media.
RESULTS: An increase in the growth of bacteria Bifidobacteria, Lactobacillus, and a consortium of bacteria selected from human milk and infant feces was noticed after pectin fermentation. It was found that pectin has a positive impact on the increase of the antioxidant capacity in all the tested samples. A high correlation was achieved, comparing electrochemical with spectrophotometric methods. Antimicrobial tests showed that pectin and fermentation products have slight or no influence at all on the growth of standard strains of Escherichia coli, Staphylococcus aureus and Candida albicans.
CONCLUSIONS: The results showed the importance of pectin as an antioxidant and its impact on the development of potential probiotic microbiota in mothers and infants. The study indicated a new potential application of pectin as a supplement in infant food.

AB  - The citric acid (CA), dextran (DEX) and (3-aminopropyl)triethoxysilane (APTES) are frequently used ligands for surface modification of magnetite nanoparticles to improve their colloidal stability and biocompatibility for use in biomedicine. Here we report the synthesis, surface modification of magnetite (Fe3O4) nanoparticles and analysis of the influence of coating materials on heating efficiency in magnetic hyperthermia, as well as on electrochemical sensing toward the detection of neurotransmitter dopamine (DOP). Spherical magnetite nanoparticles (~13 nm) were prepared by co-precipitation and surface-modified with CA, APTES and DEX. The hyperthermia tests revealed that Fe3O4@APTES resulted in the highest specific absorption rate (SAR) of 67.2 W/g. The engineered sensor, by surface modification of screen-printed carbon (SPC) electrodes with Fe3O4@APTES, showed linear response with DOP in the concentration range of 1−200 μM and a low detection limit of 34.3 nM. Besides, the sensor offered remarkable selectivity, repeatability and reproducibility. Application of SPC-, Fe3O4-, Fe3O4@CA- and Fe3O4@DEX-modified SPC electrode resulted in lower electrocatalytic activity compared with Fe3O4@APTES/SPC. The obtained results indicate the effects of a surface modifier especially that Fe3O4@APTES, alone and combining with SPC electrodes, can serve as an agent in various types of biomedical applications, like hyperthermia and electrochemical sensing of biologically active compounds such as DOP.

AB  - S-Adenosyl-L-Homocysteine (AdoHcy) is a crucial pathological factor in homocysteine-associated disorders. We developed an impedimetric approach for single drop S-Adenosyl-L-Homocysteine detection, based on S-Adenosyl-L-Homocysteine hydrolase (SAH), produced in the prokaryotic expression system (E. coli) by recombinant DNA technology, immobilized on citrate acid-coated gallium oxyhydroxide dispersed over single-walled carbon nanotubes (CA/GaO(OH)@SWCNT). The proposed biosensor offers detection of AdoHcy, with a limit of detection (LOD) of 0.17 μM. with operating linear range from 1 to 44 μM. The remarkable stability of gallium oxyhydroxide crystal was further improved by citric acid coating and its optical, electrical and physical anisotropy was skipped using SWCNTs.

AB  - Type of the wood used for the aging highly influences the quality of alcoholic beverages. In this research we explored the potential of cyclic voltammetry (CV) and differential pulse voltammetry (DPV) to establish fingerprints characteristic for each wood and to enable determining the type of the wood used in the aging process. Eleven different wood samples were used to prepare three different types of spirits during 15 months. The highest extraction rate was obtained during the first month, while further aging was followed with almost constant amount of extracted polyphenols. Black locust, myrobalan plum, and mulberry extracts were discriminated from the spirits aged in oak and wild cherry wood when statistical analysis was applied. Although clear classification of all samples was not achieved, this long term study demonstrated a potential of both CV and DPV for differentiating wood species used in the aging, hence in the quality control of spirits. © 2020 Elsevier Ltd

AB  - The goal of this work was to develop green electrode material that unites all advantages of domestic made, synthesized porous carbon powder and ceria dioxide nanoparticles known due to exceptional catalytic properties. Thermal decomposition of Novolac phenol-formaldehyde resin and cerium sulfate resulting in producing a high-performance CeO2 porous carbon material highly sensitive to dopamine (DA) electrooxidation. Morphological and structural characteristics of the material were determined by SEM and XRD measurements, while electrochemical characterization was performed by EIS and CV. The sensitivity of DA determination on the proposed CeO2-doped carbon material was enhanced by adding multi-wall carbon nanotubes to finally prepare a mixture for a specific carbon paste electrode (TPCeO2&MWCNT@CPE). SWV technique was used for quantification of dopamine in Britton-Robinson buffer pH 6 in the concentration range of 0.5-100 μM of DA, with the detection limit of 0.14 μM and quantification limit of 0.44 μM. Good selectivity overstudied bioactive compounds enables the successful and efficient application of the proposed electrode and developed an analytical procedure for the determination of dopamine in spiked urine samples.

abstract = "The goal of this work was to develop green electrode material that unites all advantages of domestic made, synthesized porous carbon powder and ceria dioxide nanoparticles known due to exceptional catalytic properties. Thermal decomposition of Novolac phenol-formaldehyde resin and cerium sulfate resulting in producing a high-performance CeO2 porous carbon material highly sensitive to dopamine (DA) electrooxidation. Morphological and structural characteristics of the material were determined by SEM and XRD measurements, while electrochemical characterization was performed by EIS and CV. The sensitivity of DA determination on the proposed CeO2-doped carbon material was enhanced by adding multi-wall carbon nanotubes to finally prepare a mixture for a specific carbon paste electrode (TPCeO2&MWCNT@CPE). SWV technique was used for quantification of dopamine in Britton-Robinson buffer pH 6 in the concentration range of 0.5-100 μM of DA, with the detection limit of 0.14 μM and quantification limit of 0.44 μM. Good selectivity overstudied bioactive compounds enables the successful and efficient application of the proposed electrode and developed an analytical procedure for the determination of dopamine in spiked urine samples.",
