A Paper-Based Photoelectrochemical Sensing Platform Based on In Situ Grown ZnO/ZnIn₂S₄ Heterojunctions onto Paper Fibers for Sensitively Detecting AFP.

After introducing biomolecules in each modification steps with CS, Ab, BSA, and AFP onto the paper-based ZnO/ZnIn 2 S 4 photoelectrode, it is notable that the PEC response displays an obvious trend, with a gradual photocurrent signal response decline of paper-based ZnO /ZnIn 2 S 4 /CS (c), ZnO /ZnIn 2 S 4 /CS/Ab (d), ZnO /ZnIn 2 S 4 /CS/Ab/BSA (e), and ZnO /ZnIn 2 S 4 /CS/Ab/BSA/AFP (f), which is due to the relative insulative proteins and distinct steric hindrance from them in the PEC bioassay process.
