A LIVING LASER

[attachment=16169]
What does it mean ??


.Living laser, a biological cell genetically engineered to produce a visible laser beam.

.Medical researchers Yun and Gather from Harvard University have succeeded in bringing this to the world.


What’s the use ??


.For Photodynamic Therapies wherein the drugs are activated by the application of light.

.Biological Imaging can improved as the laser light comes from the cell.

.Making laser beams inside the patients body to treat cancerous tissue.


Principle Behind the Living Laser


.The researchers genetically engineered the human embryonic kidney cells to produce Green Fluorescent Protein (GFP).

.They then placed a single cell(just 15 µm) between two mirrors spaced by 20 µm.


Conclusion


.Results of these experiments confirmed that it had no impact on the living cell.

.The researchers hope to integrate the structures that takes the role of mirrors into the cell to make each cell act as a standalone laser.
