Development of a Colorimetric Polydiacetylene Nanocomposite Fiber Sensor for Selective Detection of Organophosphate Pesticides.

ABSTRACT: Exposure to organophosphate (OP) pesticides is highly hazardous to human health and well-being. It has been linked to over 250,000 annual deaths connected to various chronic diseases, including cancer, Parkinson's, Alzheimer's, depression, etc. In the absence of any solid-state sensing system suitable for integration into a clothing system, an equipment-free on-site detection system for OP insecticides is essential for mitigating the severe health risks from OP exposure. This work demonstrates the synthesis, fabrication, and naked-eye and quantitative detection of OP insecticides with a polydiacetylene (PDA) ester containing the nanocomposite fiber sensor. Ester of PDA (PDA-HBA) was synthesized via facile green chemical synthesis and incorporated into a cellulosic nanocomposite fibrous ass
