Fe 3 O 4 -Au Core–Satellite Nanoparticles as Direct Colorimetric Reporters in a Smartphone-Quantified Lateral Flow Immunoassay for Prostate-Specific Antigen

2026-08-12

Abstract excerpt

<title>Abstract</title> <p>Lateral flow assays (LFAs) combine rapid operation, low cost, and direct visual detection, but their quantitative performance is often limited by the optical signal generated by conventional gold nanoparticle reporters. Sensitivity enhancement commonly relies on external excitation, dedicated detectors, or post-assay amplification, thereby increasing assay complexity. Here, Fe₃O₄/Au cor...
