Magnetic biomedical sensors and sensing systems for high- throughput biomolecular test

摘要

[ Problems ] To provide a magnetic biometric sensing system can be tested a number of specimens simultaneously . Magnetic biosensor according present invention relates includes a free layer , a fixed layer , a nonmagnetic layer between the free layer and the pinned layer . When there is no external magnetic field , at least one of the free layer or the pinned layer may have a magnetic moment that is offset from the main surface of the free layer or pinned layer . Magnetic biosensor also includes disposed specimen containers on a magnetic stack , a plurality of capture antibody attached to the bottom surface of the specimen container on the specimen stack is substantially perpendicular to the main surface of the free layer or the pinned layer to include a configured magnetic field generator to generate a magnetic field may be .
