Abstract

Recent years have seen the development of spintronic devices and their applications in biomedical areas. Spintronic devices rely on detecting or manipulating a magnetic field, a field to which biological matter is relatively transparent. The recent use of spintronic devices in biomedical areas has included diagnosing diseases such as cancer and cirrhosis, genotyping DNA, point-of-care devices, and flexible electronics. Up to date, most of the spintronic devices in biomedical applications fall into three mainstream types: anisotropic, giant, and tunneling magnetoresistance devices. Each of these has its advantages and drawbacks, which are explored and discussed in this article. The advent of spintronics gives us a new low-power, low-cost, ease-of-manufacture alternative to standard CMOS sensors. The sensitivity of spintronic biosensors has been progressing steadily, expected to increase tremendously in the next few years.

磁阻生物传感器的研究进展
近年来,自旋电子器件及其在生物医学领域的应用得到了发展。自旋电子设备依赖于检测或操纵磁场,生物物质对磁场相对透明。自旋电子设备最近在生物医学领域的应用包括诊断疾病,如癌症和肝硬化、DNA基因分型、定点护理设备和柔性电子设备。到目前为止,生物医学应用中的大多数自旋电子器件可分为三种主流类型:各向异性、巨磁电阻器件和隧道磁阻器件。每种方法都有其优点和缺点,本文对此进行了探讨和讨论。自旋电子学的出现为我们提供了一种新的低功耗、低成本、易于制造的标准CMOS传感器替代品。自旋电子生物传感器的灵敏度一直在稳步发展,预计在未来几年将大幅提高。
