Immunosensor for trace penicillin G detection in milk based on supported bilayer lipid membrane modified with gold nanoparticles.
本研究开发了一种用于痕量青霉素G电化学检测的免疫传感器。该传感器以玻璃碳电极为基底,在其表面构建支撑双分子脂质膜(s-BLM),并通过电沉积将金纳米颗粒(Au NPs)嵌入膜中,再将抗青霉素G抗体固定于修饰电极上。修饰电极经扫描电子显微镜、循环伏安法和电化学阻抗谱表征。该传感器对青霉素G具有良好的线性响应,线性范围为3.34×10−...
