In recent years, biosensing based on nanoenzymes has received widespread attention in various fields. However, most nanoenzymes with peroxidase activity exhibit excellent enzymatic activity in acidic environments but rapidly decline in neutral or alkaline environments, which poses a substantial challenge for the broader application of nanoenzymes. Currently, various methods such as doping with heteroatoms, microenvironmental regulation, and active site design have been reported to optimize the enzyme-like activity of nanoenzymes under neutral pH conditions. However, these methods have high material requirements and complex processes. Light irradiation, as an external stimulus method, can enhance catalytic performance and has the advantages of simplicity and efficiency in the field of photocatalysis. Therefore, inspired by this, developing a simple strategy based on light irradiation to regulate the enzymatic activity of nanoenzymes under neutral or weakly alkaline conditions has significant scientific significance for practical applications.
