摘要 本文利用单壁碳纳米管(SWCNTs)对凝血酶(Thrombin)适配体功能化的CdTe量子点的荧光猝灭作用及凝血酶适配体与SWCNTs相互作用的机理,通过体系中凝血酶存在与否及凝血酶浓度的高低来调控量子点荧光强度的大小,建立荧光纳米传感体系,从而实现对凝血酶的检测. This article using the interaction mechanism between thrombin aptamer and single walled carbon nanotubes(SWCNTs)which were quenching the fluorescence of thrombin aptamer functionalized CdTe quantum dots to established a kind of nanosensing system to detect thrombin.
