Bienzyme Based Biosensing Platform Using Functionalized Carbon Nanotubes

This work presents a novel approach to design an amperometric transducer capable of detecting glucose and hydrogen peroxide. The biosensor is based on a bienzyme-channelling configuration, employing the enzymes glucose oxidase and horseradish peroxidase, which were immobilized with Toluidine blue (TB) functionalized multiwalled carbon nanotubes (MWNTs). TB was covalently immobilized with carboxylic acid groups of the carbon nanotubes via...
