A xanthine biosensor was prepared by electrochemical immobilization of xanthine oxidize enzyme onto carbon paste electrode via entrapment of Bi3+. After the optimization of experimental parameters, analytical characteristics ...

In this work, glassy carbon paste electrode (GCPE) was modified with banana tissue and nanomaterials like gold nanoparticles (Au-nps) and HNO(3) treated multi-walled carbon nanotubes (MWCNTs). As a result three types of ...

We report on the determination of choline and acetylcholine via biocentrivoltammetry. This method combines centrifugation and voltammetry and is based on a carbon paste electrode modified with acetylcholinesterase and ...

Centri-voltammetry and biocentri-voltammetry are techniques that combine centrifugation with voltammetry. This review covers (a) definitions; (b) experimental (cell) configurations; (c) effects of centrifugation parameters; ...

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 ...
