Microsensor with interdigitated electrodes

Abstract

The invention pertains to a microsensor (210, 310, 410) comprising a first electrode (211, 311,411) and a second electrode (212, 312, 412), each electrode comprising a plurality of parallel tracks (222, 322, 422), each track comprising a connected end and a free end, each track extending from a strip (223, 323, 423), the strip connecting the tracks at their connected ends, the tracks of the two electrodes being offset and in mirror symmetry so that the tracks of the two electrodes are interdigitated and comprise between each pair of interdigitated tracks an assembly of nanoparticles (430) in a ligand, wherein each track (222, 322, 422) extending from the strip (223, 323, 423) comprises at least one change of direction.
