AB  - A sensitive and rapid method for the determination of fenobucarb by using screen-printed carbon electrode modified with graphene nanoribbons - ionic liquid - cobalt phthalocyanine (GNRs-IL-CoPc/SPCE) composites based on flow injection analysis (FIA) was developed and applied to vegetable samples. The prepared GNRs-IL-CoPc composite was characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and atomic force microscopy (AFM). Moreover, cyclic voltammetry (CV), differential pulse voltammetry (DPV), and electrochemical impedance spectroscopy (EIS) were used to characterize the electrochemical behavior of the modified SPCE. The amperometric current responses were obtained from the oxidation of 2-sec-butyl-phenol, which is the product of alkaline hydrolysis of fenobucarb. The optimization of chemical variables and instrumental analysis such as composite amounts, pH, applied potential, and flow rate were carried out to obtain the best measurement. Under the optimal conditions, the proposed sensor yielded sensitivity of 0.0884 M/A·cm2, a wide linear range for detection of fenobucarb from 0.025 to 110 μM with a low detection, and quantification limits of 0.0089 μM and 0.0252 μM, respectively. Additionally, the developed sensor showed good repeatability (RSD = 3.5%, n = 10 measurements) and good reproducibility (RSD = 3.9%, n = 5 sensors). The proposed method could be effectively applied for the determination of fenobucarb in vegetable samples.

AB  - An ethanol biosensor based on alcohol dehydrogenase (ADH) attached to Au seeds decorated on magnetic nanoparticles (Fe3O4"Au NPs) is presented. ADH was immobilized on Fe3O4"Au NPs, which were subsequently fixed by a magnet on a carbon paste electrode modified with 5% (m:m) MnO2. Optimum conditions for the amperometric determination of ethanol with the biosensor were as follows: working potential +0.1 V (vs. Ag/AgCl); supporting electrolyte: 0.1 M phosphate buffer solution at pH 6.8 containing 0.25 mM of the coenzyme (NAD+); working electrode: carbon paste with magnetically attached Fe3O4"Au NPs (0.012 mg . cm(-2) electrode area) with immobilized alcohol dehydrogenase (120 units per cm(2) of electrode area). Linearity between signal and concentration was found for the range from 0.1 to 2.0 M ethanol (r(2) = 0.995) with a detection limit of 0.07 M, a sensitivity of 0.02 mu A . mM(-1) . cm(-2), a reproducibility of 4.0% RSD, and a repeatability of 2.7% RSD. The results for the determination of ethanol in alcoholic beverages showed good agreement with gas chromatography (GC) with recovery of 96.0-108.8%.
