摘要：

The development of precise and efficient analysis technologies for acetamiprid (ACE) and carbendazim (CBZ) is of paramount importance for safeguarding the environment, ensuring food safety and protecting human health. In this study, we present a novel dual-channel fluorescent sensing system for the detection ACE and CBZ. This system integrates photoswitchable polymer dots (Pdots) and carbon dots (CDs) with aptamers and Fe 3 O 4 nanoparticles . Specifically, when irradiated with 465 nm excitation light, only the Pdots probe emits a fluorescent s...
