Amperometric biosensor systems prepared on poly (aniline-ferrocenium hexafluorophosphate) composites doped with poly(vinyl sulfonic acid sodium salt)
… is the development of a nanocomposite mediated amperometric biosensor for detection of hydrogen peroxide. The aim is to combine the electrochemical properties of both polyaniline and ferrocenium hexafluorophosphate into highly conductive nano composites capable of exhibiting electrochemistry in …

PEDOT Electrodes as Redox Mediators for Determination of Antioxidants in Beverages
… solutions. In the final part of this study, an amperometric biosensor has been developed to quantify specifically the phenolic antioxidant content of beverages. Tyrosinase, which oxidizes polyphenols, was physically entrapped into PEDOT during electrochemical polymerization by a cyclic …

Biocatalysis on nanostructured surfaces : investigation and application of redox proteins using spectro-electrochemical methods
… The potential of this modified material as an amperometric biosensor for the detection of superoxide anions is demonstrated. A sensitivity of about 100 A M-1 m-2, in a linear measuring range of the superoxide concentration between 0.13 and 0.67 μM, is estimated. In addition an electrochemical …
