外文摘要：We report herein the first observation of MOF nanozyme enabling dual-functional photo-induced charge transfer and biomimetic pre-cipitation for advanced organic photoelectrochemical transistor(OPECT)bioanalysis.Specifically,Fe/Co-MIL-88,serving simultaneous-ly as the semiconductor and nanozyme,was explored as a dual-functional gating module in OPECT.Upon light illumination,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.The ge-neric bioanalytical potential of such a rationale was then demonstrated with an aptasensing assisted by magnetic separation.This work represents the first exploration of biomimetic precipitation from MOF nanozymes for generic OPECT bioanalysis,it is expected to attract more interest in various nanozymes for novel optoelectronic bioanalytics.
