采用微机电系统(MEMS)技术制备出电化学微型电极芯片,并运用自组装技术修饰微型电极表面用于抗体的固定化,研制出新型的电化学微型免疫微传感器.采用MEMS技术,在硅片上制备了分别以Au、Pt、Pt为电极材料的工作电极、对电极以及准参比电极的微型三电极系统.采用自组装技术,以"Au-巯基乙胺-A蛋白"作为抗体的定向固定程序.与在平面裸电极Au表面上固定生物分子的传统方法相比,基于自组装技术的巯基乙胺修饰工作电极Au表面具有更高的生物亲和性,并且能够提高A蛋白在Au表面的固定量,从而在很大程度上提高了抗体的结合能力.研究表明,这种电化学微型免疫传感器具有检测灵敏度较高、响应快、试剂用量少、与集成电路工艺相兼容等优点.
