Solid-state proteins maximize the intensity of fluorescent-protein-based lasers

The same research team that developed the first laser based on a living cell has shown that use of fluorescent proteins in a solid form rather than in solution greatly increases the intensity of light produced, an accomplishment that takes advantage of natural protein structures surrounding the light-emitting portions of the protein molecules. The findings from investigators Seok Hyun Yun, PhD, of the Wellman Center for Photomedicine at Massachusetts General Hospital and Malte Gather, PhD, of th
