摘要
采用聚乙烯亚胺（PEI）科学仪黏附、戊二醛（Glu）交联的方法，将抗蝰蛇毒IgY固定于石英晶体表面，制成蝰蛇毒压电免疫传感器。该传感器用于检测浓度范围为0．5～100ug／mL的蝰蛇毒时，呈线性相关，相关系数为0．962，具有良好的选择性。
The anti-viper venom IgY was immobilized on the electrode surface with the methods of polyethylenimine adhesion and glutaraldehyde cross-lingking. A peizoelecric immunosensor array for the detection of viper venom was developed. The linearity of viper venom in the range from 0. 5ug/mL to 100ug/mL with the correlation coefficient of 0. 962 was obtained. Thus the immunosensor has good selectivity in the range .
