Paper-based microextraction tool for the <i>in vitro</i> and eco-friendly detection and degradation of malathion pesticide from soybean seeds.

ABSTRACT: To increase agricultural productivity, malathion is widely used as a low-cost organophosphate pesticide for soybean cultivation to protect crops from insects. The unregulated use of malathion facilitates its entry into the food chain, resulting in harmful effects on human health. Conventional sample preparation techniques are limited due to their multi-step processes and excessive solvent consumption. Here, paper-based microextraction strips were developed with phytase enzyme and divinylbenzene (DVB) and polydimethylsiloxane (PDMS) polymers for the simultaneous preconcentration of malathion and the degradation of the pesticides into less toxic phosphorodithioic acid (PDA) byproducts. The sampling strips were tested with a soybean seed matrix after spiking with 500-10000 ng mL^-1
