Core−Shell ZIF-67@CoFePBA Nanozyme with Dual Functions in PEC Signal Modulation and Fenton-like Colorimetric Catalysis for Cyfra21-1 Immunoassay
A novel dual-mode immunosensing platform integrating photoelectrochemical (PEC) and colorimetric detection was developed for the early and reliable determination of the non-small cell lung cancer biomarker cytokeratin 19 fragment (Cyfra21-1). An ordered ReS2/In2S3 type-II heterojunction array was constructed, which n...
