A Portable Electrochemical Biosensor Based on an Amino-Modified Ionic Metal–Organic Framework for the One-Site Detection of Multiple Organophosphorus Pesticides

Constructing stable, portable sensors and revealing their mechanisms is challenging. Ion metal-organic frameworks (IMOFs) are poised to serve as highly effective electrochemical sensors for detecting organophosphorus pesticides (OPs), leveraging their unique charge properties. In this work, an amino-modified IMOF was constructed and combined with near-field communication (NFC) technology to develop a portable, touchless, and battery-free electrochemical biosensor
