Infrared beam

The beam is reflected...

... thereby preventing the interference of watermolecules.

Au

Water molecules interact with the light beam and interfere with the measurement.

The molecules that are being analyzed move about freely in the liquid.

Current device New device

Infrared beam

detectionand analysis

Using an infrared beam, scientists can detect and analyze molecules contained in an aqueous solution, but only with a limited degree of precision. While she was at Boston University, Hatice Altug, now a researcher at EPFL, developed a technique of light concentration based on gold nanoparticles,which increases interactions between infrared photons and molecules. This new technique leads to a dramaticaly increased precision, and shows particular promise for medical research.
