Abstract:Among various types of biosensors, magnetoresistance-based biosensors possess several advantages including high sensitivity and being less interfered by the environment, and are therefore suitable for sensitive bio-detection. Besides, the magnetic is not shielded by chemical compounds, microstructures,or other biomaterials, so the signals detected by the magnetoresistance-based biosensors are not influenced by the surrounding objects.We present magneticnanowires and magnetized beads as a biomolecular sensing device with single cell detection possibility.The magnetic poles on the apexes and valleys of nanowires can actively attract the magnetic beads immobilized biomolecular onto the nanowires for detection.
