Development of a Rapid and Sensitive Visual Pesticide Detection Card Using Crosslinked and Surface-Decorated Electrospun Nanofiber Mat

Increased consumer awareness on food safety has spurred the development of detection techniques for pesticide residues. In this study, a rapid detection card on the basis of enzyme action was developed for the visual detection of pesticides, in which the thermally crosslinked and surface-decorated polyvinyl alcohol/citric acid nanofiber mat (PCNM) was employed as a novel immobilization matrix for acetylcholinesterase (AChE). The PCNM, crosslinked at 130 ◦C for 50 min, exhibited appropriate...
