微梁免疫传感技术是在原子力显微镜和微机电系统基础上发展起来的一项新兴传感技术,具有检测灵敏度高、无需标记、能实时原位再现生化反应过程等优点。本文针对单梁传感系统中存在的环境扰动和不能多通道检测等问题进行改进,设计制作了一种基于压电扫描的新型微梁阵列免疫传感器。利用商品化微梁阵列对传感器进行了温度测试实验,所得信号曲线稳定一致,且检测灵敏度达到2nm,实验结果验证了该微梁阵列传感系统在多通道信号检测中的可行性,为微梁阵列生化传感技术的实现提供了一种新的方案。
Micro-beam immune sensing technology is an emerging sensing technology developed on the basis of atomic force microscope and micro-electromechanical systems. It has the advantages of high detection sensitivity, no marking, and the ability to reproduce the biochemical reaction process in situ in situ. In this paper, aiming at the problems of environmental disturbance and multi-channel detection in single-beam sensor system, a new kind of micro-beam array immunosensor based on piezoelectric scanning is designed. The commercialized micro-beam array was used to measure the temperature of the sensor. The obtained signal curve is stable and consistent with the detection sensitivity of 2nm. The experimental results verify the feasibility of the micro-beam array sensing system in multi-channel signal detection. Array biochemical sensing technology to provide a new solution.
