Abstract
Abstract Engineering wearable devices for in situ and on‐site monitoring of pesticide residues from plants in a non‐destructive manner is of great research value but remains a huge challenge. In this study, a plant‐wearable fluorescence sensor CdTe CDs@PVA@AG, is designed and constructed by embedding CdTe QDs in polyvinyl alcohol (PVA) and agarose (AG)‐co‐assembled double‐network hydrogel to transmit on‐the‐scene pesticides residues messages. Harnessing red emission and stimuli‐responsive performance of CdTe QDs, as well as hydrogel's excellent flexibility, high adhesion, and porous network, CdTe CDs@PVA@AG is endowed with quantitative response to thiram at ≈µ m level within 2 min through promoting…
