利用反向微乳液技术,以CdTe量子点为核,SiO2为壳,一步制备了表面带有氨基和磷酸基团的核壳型量子点荧光纳米颗粒.该颗粒水溶性好,大小均匀,有效改善了CdTe量子点的不稳定性,抗光漂白性能大大增强.结合纳米技术、生物技术与荧光标记技术,基于硅壳包被的核壳型量子点荧光纳米颗粒,成功实现了对肝实质细胞的识别. The core-shell QDs with amino groups and phosphate groups on the surface were prepared in one step using CdTe quantum dots as nucleus and SiO2 as shell by reverse microemulsion technique. The particles were water-soluble, uniform in size and effectively improved The instability of CdTe QDs and the enhancement of anti-photobleaching properties were greatly enhanced.With the combination of nanotechnology, biotechnology and fluorescent labeling technology, based on the core-shell quantum dots fluorescent nanoparticles coated with silicon shell, Recognize.
