AB  - Microstructure and magnetic properties of nanoparticles can be tailored by optimising the synthesis procedure and changing chemical composition. In this study, a two-step procedure, i.e., coprecipitation in the presence of PEG 300 followed by microwave assisted (MW) hydrothermal synthesis, was introduced to obtain Co(x)Pe(3-x)O(4) (x = 0, 0.1 and 0.2) nanoparticles. It was found that with the increase of Co content, particle/crystallite size increased, with significant change of coercivity (H-c). The mixed samples of CoxFe3O4 (x = 0.1 and 0.2) were magnetically harder in comparison with Fe3O4. The H-c of Fe3O4 was 91 Oe, while for Co0.10Fe2.90O4 and Co(0.20)Ee(2.80) O-4, H, was 256 Oe and 1070 Oe, respectively. Saturation magnetisation (M s ) of mixed samples also increased up to 6% compared to Fe3O4. A special effort was devoted to study the effects of introducing different surfactants (PEG 300, PEG 4000 or SDS) during the synthesis procedure in order to improve morphological and microstructural properties of CoFe3O4 nanoparticles. The influence of surfactants on physical/chemical properties of nanoparticles is discussed.

AB  - A disposable glucose biosensor was prepared using nanoparticles of MnO2 decorated on graphene nanoribbons by surface modification with drop coating with the GOx and Nafion (R). Tested material was synthesized and characterized using several techniques. The biosensor could be operated under physiological conditions (0.1 M phosphate buffer, pH 7.4) and exhibited good reproducibility and stability. The linear range for the amperometric response of the biosensor at operating potential of +0.50 (versus Ag/AgCl) was from 0.1 to 1.4 mmol/l, with a detection limit of 0.05 mmol/l and high sensitivity of 56.32 mu A/mmol cm(2). Developed method was tested toward glucose quantification in real samples with satisfactory accuracy and precision.
