Abstract

A nanostructured biocatalytic interface reversibly gating electrochemical reactions upon chemical signals processed by immobilized enzymes was architectured. The chemical signals were converted to local interfacial pH changes causing restructuring of the stimuli-responsive polymer and switching ON-OFF the electrochemical reaction.
