STRAY FIELD COLLECTOR PAD AND BIO-MOLECULE SENSING MODULE AND BIOCHIP USING THE THIS METHOD

摘要

PURPOSE: A stray magnetic focusing pad and a biomolecule sensing module or a bio-chip using the same are provided to increase an active area, maintain an optimized sensor size, and increase the number of magnetic covers causing a stray magnetic field in a sensor. CONSTITUTION: A stray magnetic focusing pad focuses a stray magnetic field to amplify a magnetic flux density. The stray magnetic field(150) has a wide biomolecule sensing active area and is generated form a magnetic cover of a sensitive area.
