After self - assembling a cystamine sam on the gold electrode of the quartz crystal , the a , - at antibody has been immobilized via cross - linking with glutaraldehyde 该方法是一种很有潜力的免疫传感器抗原抗体分子固定的新方法。

It demonstrates that the results of clinical samples by this developed method are identical to those by the elisa method . 3 . a novel piezoelectric immunosensor for the antitrypsin is developed based on the self - assembled menbrane ( sam ) of cystamine 同时对人血清样品进行测定，将测量结果与酶联免疫吸附法( elisa )进行对照，以f检湖南大学硕士学位论文验法考察显示二者无显著性差异。

The main work is introcuced as follows : ( 1 ) the inorganic - organic nanocomposite of nanogold and chitosan , which have high biocompatibility , was synthesized in situ and used for the immobilization of antibodies . an amplified piezoelectric immunosensor for detection of normal human igg was designed with this nanocomposite film . comparing with self - assembling film of semi - cystamine , the inorganic - organic nanocomposite film could immobilize more antibodies with the activity of antibodis well retained 与半胱胺自组装膜比较,纳米金-壳聚糖复合物膜较大的比表面积使其可固载更多的抗体,同时可较好地保持抗体的反应活性;纳米金的物理吸附作用使更多的沉淀结合于石英晶体表面,以其为载体制备的传感器具有更大的频率响应值。
