Scientists coax gold particles to emit light strong enough to view single nanoparticles Findings have implications for tracking disease, drugs at the molecular levelResearchers in the laboratory of Boston College Chemistry Professor John T. Fourkas have demonstrated that gold particles comparable in size to a molecule can be induced to emit light so strongly that it is readily possible to observe a single nanoparticle. Fourkas, in collaboration with postdoctoral researcher Richard Farrer and BC undergraduates Francis Butterfield and Vincent Chen, coaxed the particles into strong emission of visible light using a technique called multiphoton absorption induced luminescence (MAIL).
