本文主要探讨制备用于包虫抗原DNA检测的n型多孔硅微腔生物传感器的可能性.高参杂n型硅片在HF酸/乙醇电解液中实现了具有良好性能的生物传感器基底的制备.通过检测多孔硅微腔浸入不同浓度的生物溶液前后的微腔反射谱的移动量来验证传感器的性能,溶液浓度从0.625μM至10.000μM,检测灵敏度为4.740nm/μM.当微腔基底浸泡0.625μM生物溶液后,微腔红移5nm表明制备的生物传感器是成功的.根据浓度与微腔红移量之间的线性关系表明在多孔硅传感器上检测包虫病的可行性.
This article focuses on the possibility of preparing n-type porous silicon micro-chamber biosensors for the detection of hydatid antigen DNA.The preparation of biosensor substrates with good performance in HF acid / ethanol electrolytes The performance of the sensor was verified by measuring the amount of movement of the microcavity before and after the porous silicon microcavity was immersed in different concentrations of biological solutions with a concentration of 0.625μM to 10.000μM and a detection sensitivity of 4.740nm / μM. After the 0.625μM biological solution was red-shifted by 5nm, the prepared biosensor was successful, and the linear relationship between the concentration and the red-shift of microcavity showed the feasibility of detecting hydatid disease on porous silicon sensor.
