Nanolaser Could be Implanted in the Body

Sep-25-19 A biocompatible nanolaser thinner than a human hair could be implanted inside the body to provide novel new forms of treatment and diagnosis.

The laser, from teams at Northwestern and Columbia universities, is made primarily of glass and measures between just 50 to 150 nanometers in diameter. Small enough to fit and operate within living tissue, the laser can be excited by longer wavelengths of light (able to penetrate tissue) to generate shorter wavelengths. According to the team, the key to the laser’s design is photon upconversion, which converts low-energy biocompatible infrared photons into visible laser beams by channeling the low-energy photons into a single, higher-energy unit.
