Trying to destroy cancer cells without damaging surrounding tissue and organs has been a challenge scientist have been trying to overcome for some time. A new femtosecond laser technology recently developed at the University of Tennessee's Center for Laser Applications may overcome those difficulties presented. The laser created by researchers Christian Parigger, Jacqueline Johnson, and Robert Splinter discovers, maps, and destroys cancerous cells using ultra-short light pulses.
The laser's femtosecond technology allows it to create laser light pulses that last for only one-quadrillionth of a second. The high speed allows it to be focused in on a specific area quickly and destroy any cancer cells without damaging the surrounding tissues and organs. To attack the cancer cells the intensity of the laser only needs to be temporarily increased making the procedure quick and precise.
The team also states this technology can be extremely beneficial to brain cancer patients. Parigger stated, “This treatment overcomes difficulties in treating brain cancer and tumors. And it has the promise of application to other areas, as well.” For example, the laser has the ability to permeate layers of bone such as the skull without damaging brain tissue. Currently, the team is working with the University of Tennessee Research Foundation, a nonprofit corporation, to bring their new technology to the market.
