Application Note: Performance comparison of commonly used nanoparticle probes in SARS-CoV-2 nucleocapsid protein LFA
18 February 2022

Lateral flow assays (LFAs) are simple to use, disposable diagnostic devices that can test for a wide variety of biomarkers in diverse sample types, including saliva, blood, urine, and food. Standard lateral flow tests generate an optical signal that arises from strongly colored reporter probes, often nanoparticles, bound to test lines on a white nitrocellulose strip. Given the critical role of the probes, their selection is one of the most important decisions made during the planning of a new lateral flow assay.
