Enzyme Immobilization by Hydrogen-Bonded Organic Framework for the Construction of Plant-Wearable Sensor.

ABSTRACT: It is of great significance to on-site detection of pesticides for food safety and pollution monitoring. Plant-wearable sensors (PWS) are capable of real-time detection of pesticides on crops, which facilitates the precise application of pesticides and determines whether the plant-based foods meet the criteria for safe consumption. Herein, PWS are designed by embedding an acetylcholinesterase@poly(allylamine hydrochloride)-hydrogen-bonded organic frameworks (AChE@PAH-HOF) in hydrogel discs to on-site deliver pesticide-residue information. The self-assembly of AChE@PAH-HOF, achieved via electronic interactions and hydrogen bonding with a crystalline structure-directing agent, exhibits high catalytic activity and enhances stability. To facilitate long-term and precision monitoring of organop
