SBIR Phase I: Immunoassay Bio-chip Based on a Magnetic Tunnel Junction Sensor Array

这个小型企业创新研究（SBIR）第一阶段项目旨在开发基于微观磁性隧道结（MTJ）传感元件阵列的自旋电子免疫分析技术。这种自旋电子免疫分析将使用磁性传感器的图案阵列来检测微小的磁化颗粒，这些颗粒已经被功能化以结合到特定的生物分子上。 该技术是新兴的磁免疫分析技术的开端，新的免疫分析技术的产生将产生深远的社会和经济影响。探测和识别不同的生物实体以及探测和测量技术的增加将导致能力的提高以及更大的经济和医学价值。 这项技术将对医疗保健和国土安全领域产生直接影响。

This Small Business Innovative Research (SBIR) Phase I project aims to develop a spintronic immunoassay technique based on an array of microscopic magnetic tunnel junction (MTJ) sensing elements. This spintronic immunoassay will use patterned arrays of magnetic sensors to detect tiny magnetized particles, which have been functionalized to bond to specific biomolecules. This technology is the beginning of the emerging magnetic immunoassay technologies.The creation of new immunoassaying techniques will have a far-reaching societal and economic impact. The detection and identification of different biological entities and an increased number of detection and measurement techniques will lead to improved capabilities and greater economic and medical value. This technology will have an immediate impact in the health care as well as in homeland security arenas.
