CdSe/ZnS硒化镉-硫化锌量子点标记的生物素 蛋白芯片的荧光探针的研究
CdSe/ZnS硒化镉-硫化锌量子点标记的生物素 蛋白芯片的荧光探针的研究
根据量子限制效应,当半导体荧光材料的颗粒直径减小至小于其激子的波尔直径(1—10um)时,这时的纳米粒子称为量子点(Quantum Dots,QDs),其光学性质要发生较大变化。例如,ZnS包覆的CdSe (CdSe/ZnS) QDs,量子产率达到35-50%,单个量子点的荧光强度相当于20个rhodamine 6G分子的强度,灵敏度高,可进行单个量子点的检测。如将其与生物分子如DNA,抗体等连接,可实现单个生物分子的检测。同时QD不易被光漂白。
