Carbon Coated Nanoparticles

In May of 2008, German researchers used heat as a method to try and kill cancerous cells in animals. Using a metallic iron in nanoparticles would allow for more heat (higher temperatures) to be used in this method. The coating of carbon comes in to play so as to prevent the iron from rusting.

Researchers have tested this method with normal cells to see the effects. They used Human PC-3 prostate cells and a non-malignant fibroblast cell. They incubated the cells with the carbon coated nanoparticle magnets, and no signs of cytotoxicity were found. This new method could help destroy cancerous cells without invasive surgery or chemotherapy, which can take a heavy toll on the human body.
