Surface plasmons sense carbon dioxide

The laboratory of applied optics at the Institute of Microtechnology in Neuchàtel, in collaboration with the company HachUltra Analytics, has created the first surface plasmon resonance sensor that works in the infrared range.

In an article appearing in 'Optics.org, the researchers announce that this system can detect carbon dioxide with five times more sensitivity than a system designed for visible light. The next step is to build a surface plasmon resonsance sensor system for spectroscopy in liquid media, which could be used to study biological samples.
