WebLateral flow assays (LFAs) are paper-based point-of-care (POC) diagnostic tools that are widely used because of their low cost, ease of use, and rapid format. Unfortunately, … In principle, any colored particle can be used, but latex (blue color) or nanometer-sized particles of gold (red color) are most commonly used. The gold particles are red in color due to localized surface plasmon resonance. Fluorescent or magnetic labelled particles can also be used, but these require the use of an electronic reader to assess the test result. Sandwich assays are generally used for larger analytes because they tend to have multiple bindi…
