MICROCHIP ASSEMBLY WITH SHORT-DISTANCE INTERACTION

摘要

The invention relates to a microchip assembly that is particularly applicable for biosensors. According to the invention, short-distance interactions between coupling circuits (11, 12) on a thin substrate (13) and an object (2) take place through the substrate (13) of reduced thickness (d). The coupling circuits may particularly comprise wires (11) for the generation of a magnetic field (B) and a GMR (12) for the detection of the stray fields (B') generated by magnetizing beads (2) on labeled biological molecules (1).
