nanocages.php

 New research findings suggest that an experimental ultrasensitive imaging technique that uses a pulsed laser and tiny metallic "nanocages" might enable both the early detection and treatment of disease. This composite image shows luminous nanocages, which appear like stars against a black background, and a living cell, at upper left. The gold-silver nanocages exhibit a bright "three-photon luminescence" when excited by the ultrafast pulsed laser, with 10-times greater intensity than pure gold or silver nanoparticles. The signal allows live cell imaging with negligible damage from heating. (Purdue University graphic/Ji-Xin Cheng)
