Researchers develop femtosecond laser that can diagnose, blast cancerous tumors

Researchers at the University of Tennessee's Center for Laser Applications have developed a femtosecond laser that can non-invasively diagnose, map, irradiate and burn cancerous tumors. Utilizing a beam that pulses at one-quadrillionth of a second, the technology is able to seek out growths and obliterate them with an increased burst of intensity. "Using ultra-short light pulses gives us the ability to focus in a well confined region and the ability for intense radiation," says Associate Professor of Physics Christian Parigger. "This allows us to come in and leave a specific area quickly so we can diagnose and attack tumorous cells fast." The swift, precise technique can avoiding heating up adjacent, healthy tissues and has potential for use in outpatient procedures, particularly for people afflicted with brain tumors. For now, however, the scientists are working with the non-profit University of Tennessee Research Foundation to bring their tech to market. Roll past the jump for the press release and a glimpse of the laser in action.

Another reason to buy gold: nanoparticles help to kill brain tumors

Stanford scientists have used lab-made gold nanoparticles to highlight malignant tissue in the brain, making it easier for surgeons to cut out tumors while leaving healthy bits in tact. Measuring just five millionths of an inch in diameter, these tiny glistening orbs are injected into the patient and then left to bleed out through leaky blood vessels in parts of the brain that have been damaged by the disease. They then get stuck in the bad tissue itself, marking it out for the scalpel when viewed with the right type of imaging. It's not totally new -- we've actually seen gold nanotech deployed against the Big C in stem cells before, but better to be useful than avant-garde.
