In this work, we reported PEC biosensor for formaldehyde (FA) detection based on photoinduced electron transfer (PET)-gated injection between organic and inorganic semiconducting substrates. Specifically, an FA-responsive probe (NA-FA-COOH) TiO2 nanoarrays were integrated to construct platform (NFC/TiO2) via coordination bond. NFC served simultaneously as target-specific element modulator injection. Treatment NFC/TiO2 by FA would suppress intramolecular PET process, quenched photocurrent signal due changed carrier pathway, thus establishing effective modulation. The proposed system exhibited high selectivity sensitivity, low limit 0.071 μM. This study presents novel perspective use effect advanced bioanalysis.
