摘要
磁性纳米线除了具有表面效应、量子尺寸效应、体积效应和宏观量子隧道效应等优异的纳米特性，更具有特异的磁学性能，尤其是多层纳米线的巨磁电阻效应，使其在生物医学领域具有广阔的应用前景。综述了目前阶段磁性纳米线的常规制备方法——模板合成法，包括高分子模板、多孔阳极氧化铝模板、碳纳米管模板等几种常用模板，以及磁性纳米线在模板中的不同生长方式；同时介绍了磁性纳米线在几种不同的生物传感器方面的应用，这些应用将大大改进现有的传感器测定方法，为灵敏化、快速化、自动化、多元化检测奠定基础，为生物传感器的发展开辟崭新的领域。
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 as growth 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.
