| 摘 要： | 以玻碳电极(GCE)为基底,采用恒电位法沉积一层普鲁士蓝(PB),然后将苝四甲酸二酐衍生物(PTC-NH2)自组装到其表面,形成既带氨基功能团,又可有效防止PB渗漏的导电膜.通过静电吸附和共价键合作用固定纳米金和辣根过氧化物酶(HRP)的复合物,从而制得性能优良的过氧化氢(H2O2)生物传感器.采用循环伏安法(CV)和计时电流法,考察了传感器的电化学性能.实验表明,本传感器具有灵敏度高、线性范围宽、检出限低、稳定性好、抗干扰能力强等特点.其线性范围为2.0×10-6～1.4×10-3mol/L;检出限为8.3×10-7mol/L(S/N=3).

| Abstract: | A novel type of hydrogen peroxide biosensor was prepared.First,a stable Prussian Blue(PB) film was electrodeposited on glassy carbon electrode by applying constant potential.After that,the derivative of 3,4,9,10-perylenetetracarboxylic dianhydride containing amino group was immobilized on the surface of PB by self-assembly,which can effectively prevent the leakage of PB.Then the composite of nano-gold and horseradish peroxidase(HRP-Au) was successful immobilized onto the above prepared film to construct the... |
