Lateral flow immunoassays (LFIAs) enable a rapid detection of analytes in a simple, paper-based test format, but their low sensitivity limits their applications. Here, the authors report a DNA origami-based signal amplification technology for LFIAs and apply it for the detection of cardiac troponin I in human serum.
