Engineering a Disulfide-Directed Hairpin-Shaped Antifouling Peptide for Reliable Electrochemical Detection of CA15-3 in Human Serum.
An antifouling electrochemical biosensor is constructed, which effectively resists nonspecific adsorption while maintaining high enzymatic stability, enabling the direct detection of carbohydrate antigen 15-3 in human serum with a detection limit of 2.64 mU·mL-1.
