Nanoparticle-Induced Heating Boosts Antitumor Radiation Therapy
Radiation therapy is a time-honored and effective component of modern cancer therapy, but its ultimate utility is limited by the fact that some cancer cells are resistant to ionizing radiation. Now, a research team led by Sunil Krishnan, M.D., of the University of Texas M.D. Anderson Cancer Center, has found that pretreating tumors with gold nanoparticles and near-infrared radiation dramatically improves the response of tumors to radiation therapy.
