Lateral flow tests

Lateral flow tests

Lateral flow tests, also known as lateral flow assays, are rapid diagnostic tools used to detect specific substances in biological samples. They operate on the principle of immunochromatography and are valued for their speed, simplicity, low cost, and the ability to be performed without specialized equipment.

Lateral flow tests elements

Lateral flow tests elements

Lateral flow tests consist of several components, including gold nanoparticles, nitrocellulose membranes, and humanized conjugates. The sensitivity of the results depends, in part, on the quality of the components used and the characteristics of the reporter nanoparticles produced during the detection process.

Nanoparticles

Nanoparticles

Nanoparticles are utilized as reporters in lateral flow tests because of their distinctive optical properties. They have the capacity to efficiently scatter and absorb light, allowing them to produce a strong optical signal. This signal can be interpreted visually (qualitatively or semi-quantitatively) or quantitatively using an optical reader.

Nitrocellulose membranes

Nitrocellulose membranes

Nitrocellulose membranes play a critical role in lateral flow tests, as they are responsible for retaining and detecting the tested molecule. It is important to carefully consider the properties of both the membrane and the reagent when selecting materials for an immunoassay, as their interactions significantly impact the outcome of the test.
