Google 's Alphabet has applied for a patent for a surgical laser to remove biological tissue via electromagnetic radiation . (Remember the Google contact lens for monitoring blood glucose levels?) The patent describes an " imager " that looks for high temperature sections of tissue , which is then continuously tracked by the laser - a tracker means that the tissue is allowed some freedom of motion . As always with patent filings , it is worth noting that companies routinely file patents without pursuing them any further . It 's likely that the device is under Google 's Life Sciences division , and will be aimed at treating cancers .
