Electrochemical sensing system based on coordination bond connected porphyrin-MOFs@MXenes hybrids for in situ and real-time monitoring of H₂O₂ released from cells.

ABSTRACT: Herein, the coordination bond connected porphyrin-MOFs/MXenes composites has been prepared to construct an electrochemical sensing system for in situ and real-time monitoring of H₂O₂ released by cells. The composites were synthesized by introducing 4-mercaptopyridine and utilizing its binding interaction with titanium in Mxenes and iron in MOFs. This composite was then transferred to the surface of ITO to construct an electrochemical sensing system. The unique properties of Mxenes and porphyrin MOFs endowed the sensing system with excellent electrocatalytic activity, good electrical conductivity and desirable biocompatibility. The electrochemical detections of hydroquinone verified the superior electrochemical performances of the sensing system. The constructed system
