| Mar 9, 2015 at 20:35 | comment | added | Twelfth | Article :The team engineered human embryonic kidney cells to produce GFP, then placed a single cell between two mirrors to make an optical cavity just 20 micrometres across. When they fed the cell pulses of blue light, it emitted a directional laser beam visible with the naked eye — and the cell wasn't harmed. The width of the laser beam is "tiny" and "fairly weak" in its brightness compared to traditional lasers, says Yun, but "an order of magnitude" brighter than natural jellyfish fluorescence, with a "beautiful green" colour. nature.com/news/2011/110612/full/news.2011.365.html | |
