压电免疫传感器作为一种新型生物传感器，是利用压电元件的质量敏感性质，结合生物免疫识别特性而形成的一种自动化分析检测传感器，它可对多种抗原或抗体进行快速的定量测定，并可用于反应动力学的研究。具有高特异性、高灵敏度、响应快、小型简便等特点。本文利用石英晶体产生体波厚度剪切振动模式，由双通道系统进行频率变化的测定。采用氨基硅烷膜固定抗体来定量检测溶液中人体免疫球蛋白IgG的含量。
As a new type of biosensor, piezoelectric immunosensor is an automated analytic sensor that utilizes the mass-sensitive nature of piezoelectric elements in combination with bioimmunological identification to rapidly quantify multiple antigens or antibodies, And can be used for the study of reaction kinetics. With high specificity, high sensitivity, fast response, small and simple and so on. In this paper, quartz crystal is used to generate bulk wave shear vibration mode and the dual-channel system is used to measure the frequency variation. Aminosilane membrane immobilized antibody was used to quantitatively detect the content of human immunoglobulin IgG in the solution.
