Michigan State University (MSU) announced that it has developed a new laser technology that allows doctors to scan the mole of a patient in a non-invasive and painless manner.
Smart laser technology being developed to scan a patient's mole
MSU carried out the research with the help of the National Science Foundation, which has partially funded the project.
The new smart laser technology features laser microscopes, which deploy ultra-short pulses to detect molecules. Marcos Dantus, Professor of MSU, stated that the smart laser technology allows users to excite compounds selectively. He added that the technology ahs the ability to shape the lasers’ pulse and excite the compounds based on the vibrational signatures.
The technology also allows researchers to examine the penetration of compounds inside the hair and skin closely. Dantus also utilizes the smart laser technology to identify hazardous substances from long distances. The technology’s results have been published in Nature Photonics magazine.
