Interface-Adaptive Dual-Color Hydrogel with Self-Repairing Function and High Adhesion as Flexible Wearable Sensor for Minimally-Invasive Monitoring Pesticide Residue in Living Crop.

ABSTRACT: Harnessing dandy mechanical property, hydrogels facilitate the construction of wearable fluorescence sensors for minimally-invasive monitoring pesticide residue in living crops, while the interface self-adaptability and detection accuracy remain hugely challenging. Herein, blue-emission aggregation-induced emission nanoparticles (b-TPE NPs) and red-emission Mn-doped ZnS quantum dots (r-Mn@ZnS QDs) are encapsulated inside agarose, borax, and polyvinyl alcohol-co-constituted hydrogel to construct dual-color TPE@Mn@ZnS@AG@PVA as wearable crop sensor. Owing to specific recognition of r-Mn@ZnS QDs by thiophannate-methyl (TM), the customized TPE@Mn@ZnS@AG@PVA shows a gradual color evolution from reddish purple to blue with high resistance to environmental and experimental interferences via quenc
