A Silver Nanoparticle Mirror (IMAGE) University of Utah Caption A silver nanoparticle mirror is held next to a US penny for scale. University of Utah physicists and chemists developed a new microscope method for looking at the internal structure of certain biological materials using "hotspots" of bright white light generated when the silver nanoparticles are hit with infrared laser light. The method also could be used to routinely check the integrity of a new generation of aircraft with fuselages, wings and tails made of carbon fiber. Credit John Lupton, University of Utah.
