Abstract
Lateral flow immunoassays (LFAs) are widely used platforms for point-of-care detection of target analytes; however, these rapid tests are not very sensitive and offer only binary results. In this study, highly sensitive thermo-photonic LFA readers were developed for the sensitive detection and quantification of tetrahydrocannabinol (THC) in oral fluids and the antibodies (IgM and IgG) developed against SARS-CoV-2 virus in human blood/plasma. Our results suggest developed readers not only improved the detection limit by more than an order of magnitude, but also enables reliable quantification of target analytes.
