Advance in preparation of magnetic nanowires and its application in biosensors / 国际生物医学工程杂志

ABSTRACT

Magnetic nanowires not only have nanometer properties, but also have magnetic property of giant magnetoresistance. Recently, nanowires were applied widely in high density hard disk slider, super magnetic storage element, micro-sensors, micro-engine, biomedical engineering, etc. This artical reviews the current preparation method of nanowires, the template synthesis, including several general templates such as track-etched porous polycarbonate membrane, porous anodic aluminum oxide membrane and carbon nanotubes, as well asgrowth patterns of nanowires in the templates. The applications of nanowires in several biosensors are introduced.The applications will greatly improve current ways of sensor detection, which will open up new areas of the field of biosensor study.
