GFP helps turn single cell into “living laser”

Compiled by BioPhotonics staff

For the first time, a single living cell has been genetically engineered to produce nanosecond pulses of laser light. The “living laser,” developed by two researchers at the Wellman Center for Photomedicine at Massachusetts General Hospital, is a single cell genetically engineered to express green fluorescent protein – originally found in a species of jellyfish – that amplifies photons into a visible laser beam. Lasers have used synthetic gain materials such as gases, crystals and dyes to amplify photon pulses. Now the scientists are using GFP as the gain...Read full article
