Metallic nanoparticles can kill cancer cells leaving healthy ones intact, say researchers

Metallic nanoparticles made from silver and copper can kill cancer cells with minimal or little side effects, say researchers from the Middle East. A study published in Advanced Biology showed that the metallic particles "were significantly toxic to cancer cells, while having no significant toxicity on healthy cells," according to Prof. Yousef Haik of the University of Sharjah.
