The effects of nano-silver on the proliferation and cytokine expression by peripheral blood mononuclear cells.

Silver could prove to be a valuable alternative raw material for antibiotics and disinfectants as it is relatively free of adverse effects. Nano-silver is now been put to practical use in commonly used items, such as, clothes, electric home appliances, and electronic industry, but has not been widely applied in the medical or pharmacological fields. This study was designed to investigate the effects of nano-silver on the production of cytokines by and on the proliferation of peripheral blood mononuclear cells (PBMCs).
