Abstract (en)
[origin: FR2757949A1] The invention concerns a micro system for biological analysis for detecting analytes, for example antigens, in a sample. The micro system comprises: an isolating substrate (1) coated with a first conductor (3) forming a first electrode, and a second conductor (7) bearing a plurality of conductive elements (7) extending above the first conductor so as to form a second coplanar electrode arranged at a distance <u>d</u> from the first conductor; and means (13, 15) for polarising the first and second conductors. The electrode(s) are covered with a specific ligand. After a sample has been introduced on the substrate, the presence of analyte in the sample can be detected by measuring the impedance between electrodes 3 and 7, which will indicate the formation or not of an analyte-ligand layer on the electrode(s).
