ON-CHIP MAGNETIC PARTICLE SENSOR WITH IMPROVED SNR

摘要

A device and method is disclosed for the detection or determination of the presence of magnetic particles (15), such as for example, but not limited to, magnetic tiano­particles. In particular it relates to an integrated or on-chip magnetic sensor element (11) for the detection of magnetic particles. The device and method of the present invention o er high signal-to-noise ratio and low power consumption and do not require an external magnetic field. They may be used for magnetic detection of binding of biological molecules on a micro-array or biochip.
