Our technology is based on the functionalization of magnetic particles of only a few hundred nanometers in diameter, to which we add on its surface antibodies capable of binding to certain bacteria. In the case of Legipid®, the antibodies are able to recognize and bind only to the Legionella present in a water sample. It is a quick and effective way to know if this bacteria is present in the sample being analyzed.
Then, once the bacterium is captured, we reveal its presence through an enzyme conjugated to a second antibody that binds only to the present Legionella. This enzyme is able to generate a color that increases with the amount of Legionella present in a sample.
