摘要

在未来，需要基于芯片实验室的设备，紧凑和廉价的检测单元，直接将某些生物分子的丰度转化为电子信号。通过用磁阻传感器检测特定结合的磁性标签，可以设计一个多功能平台，满足这些要求，甚至可以通过合适的磁场梯度在芯片上操纵生物分子。本文讨论了基于巨磁阻(GMR)的磁阻传感器对磁性标签的灵敏识别。

Giant magnetoresistance material and its potential for biosensor applications

In the future, devices based on lab-on-a-chip, compact and inexpensive detection units are required that directly translate the abundance of certain biomolecules into an electronic signal. By detecting specifically bound magnetic labels with magnetoresistive sensors, a versatile platform can be designed that fulfils those requirements and even enables on-chip manipulation of biomolecules by suitable magnetic gradient fields. In this paper, sensitive recognition of magnetic label by magnetoresistive sensor based on giant magnetoresistance (GMR) have been discussed.
