MagIA Diagnostics, a startup spun off from G2Elab, LMPG, Institut Néel, and IAB in 2017, develops fast, easy-to-use immunological tests that will enable tests currently completed in laboratory settings to be completed anywhere.
Unlike the traditional ELISA (enzyme-linked immunosorbent assay) test, MagIA’s technology does not require wash steps. An antigen associated with a given pathology is detected using antibodies marked with magnetic nanoparticles and others with fluorescent particles. If the antigen is present in the sample, in less than fifteen minutes it bonds to the antibodies, forming magnetically-marked compounds that are captured locally using micromagnets. The unique signal is distinguished from the supernatant using a differential imaging system.
