Turn-On Near-Infrared Lateral Flow Immunoassay with Synergistic Energy Transfer for Direct and Ultrasensitive Detection in Complex Matrices.
The rapid, sensitive, and quantitative detection of small-molecule analytes in complex matrices remains fundamentally constrained by severe optical interference and limited signal transduction efficiency. Herein, we report a turn-on near-infrared (NIR) fluorescence lateral flow immunoassay (NFLFIA) that integrates indo...
