Four U.S veterinary teaching hospitals are conducting clinical trials to evaluate gold nanoparticles combined with targeted laser treatment for solid tumors in cats and dogs. The procedure involves infusing the animal with gold nanoparticles that congregate in the vasculature of tumors but otherwise clear the body within 36 hours. Then clinicians use targeted laser treatment to heat the particles in an effort to damage the tumor cells. The treatment is promising and could be useful in humans, bur more research is needed.
