'Nanostars' Could Be Ultra-sensitive Chemical Sensors

KurzweilAI.net, April 19, 2006

New optics research from Rice University's Laboratory for Nanophotonics suggests that gold nanoparticles called nanostars could become powerful chemical sensors.

Nanostars combine some unique qualities with some of the best properties of photonic particles like nanorods and quantum dots. They deliver strong spectral peaks that are easy to distinguish with relatively low-cost detectors, but unlike other particles, each spike on a nanostar has a unique spectral signature that could be useful for 3-D molecular sensing.
