英文摘要Quorum sensing signal molecules (3-O-C10-HL) regulate marine biofouling on artificial substrates, necessitating a quick detection method to track its onset and development. In this study, an innovative NH2-UiO-66/CdS gated organic photoelectrochemical transistor (OPECT) biosensor was contrived and deployed for the sensitive detection of 3-O-C10-HL, employing an exonuclease (Exo) III-facilitated enzymatic amplification strategy for the manipulation of cDNA. Notably, the NH2-UiO-66/CdS type II heterojunction was meticulously synthesized and demonstrated their proficiency in modulating the poly(3, 4-ethylenedioxythiophene): polystyrene sulfonate channel. The specific adsorption of 3-O-C10-HL to the self-screened aptamer elicited the release of cDNA, which in turn engaged in an Exo III-mediated enzymatic cycling process, culminating in the formation of magnetic beads/dsDNA3-Au nanoparticals@ascorbic acid-2-phosphate (AAP) complexes. The subsequent coalescence of these complexes with AAP resulted in the production of the electron donor ascorbic acid, thereby enhancing the photoconversion efficiency of NH2-UiO-66/CdS photoelectrode and modifying the channel current response. Remarkably, the fabricated device manifested a current amplification of 1150, a linear detection range spanning from 10-3 to 10-9 M, and an impressive detection limit of 0.967 pM. This study introduces an innovative methodology for the detection of 3-O-C10-HL, which paves new avenues for the effective surveillance of the onset and progression of marine biofouling.
