Researchers Create Working Nano Laser

Zothecula writes "Researchers at Northwestern University have developed a laser the size of a virus particle that can operate at room temperature. The 'nanolaser,' which uses gold nanoparticles instead of mirrors, is claimed to be the first demonstration to make use of a so-called bowtie arrangement of metal nanoparticles, though nano-scale lasers have been previously demonstrated."

That's great. Seems to be wonderful. But what will it be used for / with ? What industry will benefit of this "invention" ?

Funny, they asked the same things when lasers themselves were invented. Nowdays, how many lasers are in your house? The fact is, you never know when a "useless" invention or discovery will turn out to be earth-shaking.
