Ratiometric Fluorescent Lateral Flow Immunoassay for Point‐of‐Care Testing of Acute Myocardial Infarction

Ratiometric fluorescent lateral flow immunoassay is achieved by inner filter effect-mediated double-signal-reverse change, which not only enables highly sensitive quantitative analysis by combing with the smartphone platform, but also allows the visual readout of H-FABP concentration by the naked eye. The developed strip can be used for rapid and accurate point-of-care testing of acute myocardial infarction.
