The performances of graphene oxide (GO) and graphene-platinum hybrid nanoparticles (Gr-Pt hybrid NPs) were compared for biofuel cell (BFC) systems. This is the first study that constitutes these nanomaterials in BFC systems. ...

The electroanalytic performances of glassy carbon paste electrode (GCPE), multi-walled carbon nanotube (MWCNT)-GCPE and double-walled carbon nanotube (DWCNT)-GCPE, which include HNO3 washed/unwashed materials, were compared ...

A composite electrode was prepared by modifying glassy carbon micro particles with gold nanoparticles and glucose oxidase enzyme for glucose detection. In terms of analytical characteristics, a linearity was obtained in ...

A biosensor was developed using glutathione peroxidase (GSH-Px) as the enzyme. Firstly, platinum (Pt) nanoparticles were deposited onto a glassy carbon paste electrode (GCPE), and then GSH-Px was immobilized by means of ...

This paper presents a comparative study of nanomaterial modified glassy carbon paste electrodes (GCPEs) used as bioanodes in enzymatic biofuel cells. The developed bioanode electrodes were obtained by modification of ...

In this study, manganese(IV) oxide (MnO2) nanoparticle (np)-modified glassy carbon paste electrode is used for ascorbic acid (AA) detection in fruit juice samples. The experimental parameters like MnO2 np amount and pH ...

In this work, an enzymatic biofuel cell (BFC) was developed by combining nanomaterial modified and plain glassy carbon paste electrodes (GCPE). Because of the composite nature of GCPE, very practical and economic bio-anode ...

In the present study, simple and sensitive voltammetric determination of caffeine was carried out by using a gold nanoparticle-glassy carbon paste composite electrode (AuNP-GCPE) in 3.2 mM H2SO4 (pH 2.5). The effects of ...
