Energy transfer: Dye lasers with a difference.

The article informs that designs of dye laser can be identified with the help of Förster resonance energy transfer. It mentions the benefits of laser dyes which include deep tissue penetration, low photoinduced damage and reduced interference from the autofluorescence of biological samples. It presents a figure of a polymer core-shell nanoparticle which has been loaded with rhodamine and Nile blue dyes.
