The Scientists Designed a Tiny Nanolaser Able to Operate Inside Living Bodies Tissues

The Northwestern and the Columbia Universities scientists have constructed a new type of a tiny laser being fully biocompatibility and able to work inside tissues of living bodies without damaging them. This 150 nm laser consumes very little energy and may become a base of new diagnostics technologies, prevention techniques and practices of healing neurological diseases etc.

Such lasers will make it possible to fight malignant cells and remove malignant tissues from nooks, inaccessible through other means. Simultaneously, they can break down toxic proteins, giving development to Alzheimer's and Parkinson's diseases.

In the process of a new nanolaser construction scientists applied the so-called photon upconversion method, which lets form a single high-energy photon by absorbing several low-energy photons. Upconversion makes low-energy infrared photons turn into visible range photons of light.
