A piezoelectric immunosensor for detection in liquid phase was developed by using polyethy_leneimine method for immobilization C2 type staphylococcin enterotoxin antibody on the gold electrode of rough piezoelectric crystal and dual modulated oscillator. The immunosensor has fair stability and specificity. 利用聚乙烯亚胺法,将C2型葡萄球菌肠毒素(SE)抗体固化在未抛光的压电晶体的金电极上,利用双调式振荡电路制作的振荡器,构建压电免疫传感器,其稳定性、特异性都较好。
