From the wire: Researchers at Chalmers University of Technology in Sweden have developed a new measurement technology that makes use of the optical resonances in nanoparticles. The method, which opens up new possibilities in the field of catalytics, will be described in detail in the Science journal in November.
Optical resonances in nanoparticles, which are known as “plasmon resonances,” have been the object of intense research; scientists are working on using the technique for the detection of biological molecules.
The Chalmers scientists can now show that plasmon resonances in nanoparticles can be used to monitor reactions on catalysts and for the design of hypersensitive sensors.
With the new technology it will be possible to study catalysts in real time under realistic conditions, thus enhancing knowledge of catalytic processes and helping develop new catalysts. The novel sensors could potentially be used in a variety of application including medical diagnostics.Brian Buntz
