A carbon dot-based fluorescence turn-on sensor for hydrogen peroxide with a photo-induced electron transfer mechanism

Abstract

A carbon dot-based fluorescence turn-on sensor for hydrogen peroxide (H2O2) with a photo-induced electron transfer mechanism was developed. The sensor exhibits good selectivity, sensitivity, and rapid response to H2O2 with a detection limit of 84 nM. The sensor maintains excellent sensing performance over a wide pH range.
