Smart lasers for painless cancer biopsies

Facebook X LinkedIn Email
Compiled by BioPhotonics staff

Rather than cutting slivers of skin to send to a lab for testing, a development in smart lasers could make biopsies painless and noninvasive. Using a laser microscope that deploys rapid, ultrashort pulses to identify molecules, doctors soon could have a painless tool to scan a patient’s troublesome mole and review it on the spot. Scientists at Michigan State University shaped the pulse of the smart laser to excite one compound or multiple compounds, based on their vibrational signatures, resulting in significant contrast. Although researchers previously used fluorescent compounds...Read full article
