Researchers in the US say they have succeeded in tuning the wavelength of light emitted by a tiny laser made from plasmonic nanocavity arrays. The plasmon laser, which consists of arrays of gold nanoparticles surrounded by dye molecules dispersed in a liquid, is robust and can operate at room temperature. An important use for the new device could be detecting cancer biomarkers at very low concentrations, say the scientists.
