Electrochemical pretreatment of amino-carbon nanotubes on graphene support as a novel platform for bilirubin oxidase with improved bioelectrocatalytic activity towards oxygen reduction.

Abstract

The electrochemical conditioning of amino-carbon nanotubes (CNTs) on a graphene support in an alkaline solution is used to produce -NHOH as hydrophilic functional groups for the efficient immobilization of bilirubin oxidase enzyme. The application of the immobilized enzyme for the direct electrocatalytic reduction of O2 is investigated. The onset potential… (More)
