摘　　要：We report herein the first observation of MoF nanozyme enabling dual-functional photo-induced charge transfer and biomimetic precipitation for advanced organic photoelectrochemical transistor(OPECT)bioanalysis.Specifically,Fe/Co-MIL-88,serving simultaneously as the semiconductor and nanozyme,was explored as a dual-functional gating module in OPECT.Upon light llumination,it could accelerate the charge transfer of the photogate to produce enhanced photo-induced voltage.Meanwhile,its catalytic property could efficiently produce biomimetic precipitation to block the nanopores in Fe/Co-MIL-88 and thus alter the device characteristics.
