Magnetic fluid-modeled microgravity: A novel way to treat tumor

With the advances of nanotechnology in recent years, our understanding of the therapy of cancers has deepened and the development of new technologies for cancer diseases has emerged. Here, with the recent discoveries of nanomagnetic fluids as well as microgravity effects upon cancerous cells, we suggest an innovative method of treating tumor using magnetic fluid-modeled microgravity. Magnetic fluids are delivered by outside magnetic field to tumor issue either intravenously or through direct injection, and this is followed by application of an uniform external magnetic field that causes microgravity. The modeled microgravity is to inhibit cancerous cells growth and invasion. (C) 2011 Published by Elsevier Ltd.
