Nanozymes open up new avenues for amplifying signals in photoelectrochemical (PEC) biosensing, which are yet limited by the generated small-molecule signal reporters. Herein, a multifunctional nanoenzyme of Pt NPs/CoSAs@NC consisting Co single atoms on N-doped porous carbon decorated with nanoparticles is successfully synthesized cascade catalytic polymerization dopamine constructing highly sensitive photocurrent-polarity-switching PEC biosensing platform. Taking protein tyrosine phosphatase 1B (PTP1B) as target model, nanoenzymes linked to magnetic microspheres via phosphorylated peptides. Upon dephosphorylation PTP1B, multiple enzyme-like activities, including peroxidase (POD)-like, catalase (CAT)-like, and oxidase (OXD)-like released collected induce situ ZnCdS photoelectrode presence H
