In Situ Engineering of S-Scheme Bi2O3/Zn3In2S6 Heterojunctions on Paper-Based Architectures for Dual-Mode Photoelectrochemical-Electrochemical Detection of Carcinoembryonic Antigen.
A highly sensitive dual-mode immunosensing platform, integrating photoelectrochemical (PEC) and electrochemical detection via the in situ architectural engineering of an S-scheme Bi2O3/Zn3In2S6 heterojunction directly onto cellulose fiber scaffolds, which represents a versatile architecture for the early diagnosis of diverse clinical biomarkers.
