SYSTEM FOR SIGNAL DETECTION OF SPECIMEN USING MAGNETIC RESISTANCE SENSOR

摘要

PURPOSE: A system for detecting the signal of a specimen is provided to detect the variation of a magnetic component in the specimen using a magnetic resistance sensor and an external magnetic field application device. CONSTITUTION: A fixing unit(120) fixes a specimen which is combined to a magnetic particle. An external magnetic field application device(110) applies an external magnetic field to the specimen. A magnetic resistance sensor(130) detects the magnetic component of the specimen which is combined to the magnetic particle based on the external magnetic field.
