In the battle against cancer, Virginia Tech researchers have developed a potential warhead to better kill cancer cells, a new missile to deliver the warhead more efficiently to the diseased areas, and a new detonation device once the warhead is in place.
In a cross-disciplinary effort, the researchers, using photodynamic therapy (PDT), have obtained results in three different areas that, used together, have the possibility of providing more efficient, less invasive, and more specific treatments for cancer and other diseases such as age-related macular-degeneration.
A long-term concept has held that one should be able to use light-activated compounds to kill diseased cells, said Karen Brewer, associate professor of chemistry. The researchers have developed new tri-metallic supra-molecules that can be positioned in exact parts of cancer cells and excited by a therapeutic wavelength at which light propagates efficiently through tissue. Only when the light hits the supra-molecules do they become toxic to the cancer cells.
