lateral flow

Lfa Antibody Toponly Sm

Using a strip of porous membrane material as a platform, we can employ our liposome technology in the detection of target analytes in a lateral flow assay format. This format lends itself for inexpensive, rapid and extremely simple to use devices for point of care diagnostics, resource-limited settings and alike. Employing liposomes in this format allows for the visual detection of as little as 1 fmol of RNA.
