Cytotoxic Activity of Highly Purified Silver Nanoparticles Sol Against Cells of Human Immune System
In this clinical study, published in the journal Applied Biochemistry and Biotechnology in April 2015, researchers found that when human promyelocytic leukemia cells (HL-60) and “human monocyte cells” (U-937) from a lymphoma cancer cell line were exposed to silver nanoparticles of 25 ppm concentration, the “viability of HL-60 cells (i.e., leukemia cells) diminished to about 60 % in the presence of AgN at concentration of 25 mg/l regardless of the length of the exposure time.
At the same silver sol concentration, viability of U-937 cells decreased to about 70 % after 24 and 48 hours and to about 20% after 72 hours.” In other words, the ability of the cancer cells to maintain their life spans were significantly reduced after application of the silver nanoparticles. The researchers concluded that, “…nanosilver particles may be considered as a support for anticancer therapy.”
