Ca9Sr（ PO4）6（OH）2 nanopartides were prepared through homogeneous precipitation method. Strontium hydroxide, calcium hydroxide solation and monocalcium phosphate were used as initial materials. The strontium-doped hydroxyapatite nanoparticles were characterized by XRD, PCS and AFM. The nanoparticles were applied to interact with human bepatocellular carcinoma cells Bel-7402 and nornud liver cells L-02. Experimental results revealed that nano strontium-strontium apatiw has different bioeffects on proliferation of these two kinds of cells.展开更多

Various techniques, including the methylthiazolyldiphenyl-tetrazolium bromide assay, the real-time cell electronic sensing system, the optical and fluorescence imaging, and electrochemical methods have been utilized to study the potential interactions of Cys-CdTe QDs with Qu. The observations demonstrate that the safe-dosage Cys-CdTe QDs can greatly improve the drug uptake and enhance the inhibition efficiency of Qu towards the proliferation of cancer cells such as HepG2 cells. This study implies that Cys-CdTe QDs may be used for cancer therapy and that they exert a synergic anticancer effect when bound to drug molecules.展开更多
