Using Human Cells and Jellyfish Protein, Researchers Build the First Living Laser

Monday, June 13, 2011 - 14:00 in Physics & Chemistry

A bright future for internal medicine Researchers at Harvard Medical School and Massachusetts General Hospital built a living laser partly to study interactions between electronic and biological systems, and partly out of sheer curiosity. The world's first biological laser, made from a single living cell, could lead to better microscope imaging inside the body and even targeted light therapies, researchers say. A single human cell engineered to express green fluorescent protein can be used to amplify photons into super-short pulses of laser light, the researchers say.
