Syntheses of amorphous and crystalline cupric sulfide nanoparticles and study on the specific activities on different cells.
نویسندگان
چکیده
Copper sulfide amorphous nanoparticles and nanocrystals were prepared successfully by a special process. These CuS nanoparticles could specifically and significantly induce the apoptosis and inhibit the proliferation of human cancer cells rather than normal cells. Moreover, the biological activities of these nanoparticles are related to their polymorphs.

Syntheses of amorphous and crystalline cupric sulfide nanoparticles and study on the specific activities on different cellsw
Recently, with the development of nanoscience and nanotechnology, the potential application of inorganic nanomaterials in life sciences has become increasingly extensive, such as the fluorescent biological labeling of cells, drug and gene delivery, biological detection of pathogens and proteins, and probing of DNA structure. This leads to considerable concerns about the biological effects of th...
متن کاملEvaluation of Toxic and Teratogenic Effects of Zinc Sulfide (Zns) Nanoparticles on Chicken Embryos and Fibroblastic Cells Culture
Aims: Nanoparticles (particles with a diameter of 10-500 nm) are currently used in the cosmetics industry, as well as for pharmaceuticals, diagnostic imaging and tissue engineering. Since these nanoparticles are used in industry and drug delivery, it can also be used by pregnant mothers. Hence, the aim of the present study was to investigate the teratogenic and cytotoxic effects of Zinc sulfide...
متن کاملZSM-5 Zeolite As Host Material for Semiconductor Nanoparticles
This work describes the optical and structure properties of nickel sulfide and cobalt sulfide nanoparticles in ZSM-5 zeolite. The samples were obtained by sulfidation of the Ni2+ and Co2+ ion-exchange ZSM-5 zeolites in a Na2S solution at room temperature. The optical properties of the samples were studied by UV-visible spectroscopy. Their crystalline structure and morphology were studied by X-r...
متن کاملSelective Phagocytosis of Crystalline Metal Sulfide Particles and DNA Strand Breaks as a Mechanism for the Induction of Cellular Transformation1
Crystalline NiS, CuS, CoS2, and CdS particles were actively phagocytosed by cells and potently induced morphological transformation of Syrian hamster embryo cells in a concentra tion-dependent fashion. In contrast, the respective amorphous metal sulfide particles (amorphous NiS, CuS, CoS, and CdS) were not as actively phagocytosed by cultured cells and, in comparison to the crystalline form of ...
