Ag/CuTb2O2 nanozyme-based dual-mode biosensor with self-validating function for ultrasensitive detection of organophosphorus pesticides.
In this study, a dual-mode electrochemiluminescent-colorimetric (ECL-colorimetric) biosensor based on Ag/CuTb2O2 nanozyme was developed for the ultrasensitive detection of trichlorfon and other organophosphorus pesticides (OPs) by inhibiting acetylcholinesterase (AChE). The Ag/CuTb2O2 composite, prepared via electrospi...
