Scientists Create Single-Cell Living Laser

Scientists have managed the create the world’s first ‘living’ laser using a light producing protein from a jellyfish.

According to an article on the BBC, Malte Gather and Seok Hyun Yun at the Wellman Center for Photomedicine at Massachusetts General Hospital in the US were responsible for the surprising breakthrough.

The researchers started by creating a living cell that produces light. The cells was taken from a jellyfish that is able to produce its own light. They then passed blue light through the cells which created green coloured, directed laser light.

The researchers claim that the resultant technology can not only improve microscopic imagery but can also improve light based therapy.

The cells remained alive during and after the entire process indicating that the living laser has a self healing system that can regenerate the cells.

"In cellular sensing, we may be able to detect intracellular processes with unprecedented sensitivity," the researchers said to the press.

"For light-based therapeutics, diagnosis and imaging, people think about how to deliver emission from an external laser source deep into tissue. Now we can approach this problem in another way: by amplifying light in the tissue."
