Single-atom catalysts integrated with semiconductors for constructing a dual-potential electrochemiluminescence sensor for intracellular H2O2 detection

Single-atom Co-doped g-C 3 N 4 was combined with MoS 2 to synthesize a MoS 2 /g-C 3 N 4 composite, used here for the first time to develop a dual-potential electrochemiluminescence (ECL) sensor for intracellular H 2 O 2 detection.
