New optical device could help detect drugs, bomb-making chemicals and more

A University at Buffalo-led team of engineers has developed a new device for surface enhanced infrared absorption (SEIA) spectroscopy. Infrared light is trapped by tiny gaps in the device's metal surface, where it can be used to detect trace amounts of matter. The SEIRA advancement could be useful ...This is an NSF Multimedia Gallery item.
