Today, it is standard practice to detect many diseases through MRIs, PETs, X-rays, or CAT scans. But all of these medical imaging methods include some risk of radiation and take hours – if not days – to get results. Most importantly, the level of information they provide is lacking because it is not at the molecular level. Raman spectroscopy, a tool previously used to provide molecular information in science, is now being used in medicine and biomedicine to provide an optical biopsy that offers more detailed, faster detection. This novel, less invasive way of detecting disease using light
