A novel peptide electrochemical biosensor for heparin based on the dual “turn-on” signals of Ag/2D CuTCPP(Fe)

Herein, a "turn-on" peptide-based electrochemical biosensor was developed for the dual-signal sensing of heparin employing Ag/2D CuTCPP(Fe). Our method with high analytical performance was exploited in the accurate quantification of heparin in rat serum throughout its metabolic process.
