Composition, device, system, and methods for detecting environmental toxicants

Abstract

Disclosed herein are aspects of a composition for detecting environmental toxicants such as, but not limited to, perfluorinated-alkyl substance, perfluorooctanoic acid, and the like. The composition allows for the rapid, sensitive detection of perfluorinated-alkyl substances (PFAS) by utilizing the competitive interactions during capillary action. The composition comprising one or more cellulose fibers; and one or more biomolecules associated with the one or more cellulose fibers, wherein the composition is configured so that when the composition contacts the liquid sample, the one or more biomolecules disassociate from the one or more cellulose fibers by interacting with the one or more environmental toxicants thereby decreasing the flow of the liquid sample comprising one or more environmental toxicants. A system for using the composition is also disclosed along with a method of using the paper microfluidic chips and a method making the paper microfluidic chip.
