Modified carbon nitride nanozyme as bifunctional glucose oxidase-peroxidase for metal-free bioinspired cascade photocatalysis

Abstract

Glucose oxidase (GOx) and horseradish peroxidase (HRP) are used as an enzymatic cascade for blood glucose monitoring. Here, the authors developed a metal-free, graphitic carbon nitride-based nanozyme with GOx- and HRP-like activities and combine it with a microfluidic reactor for real-time glucose monitoring.
