A new cheap and efficient method to improve SERS

Read the news from NANOWERK.com

Materials Today´s cover highlights the research work ("Reliable and cheap SERS active substrates") developed by CiQUS researchers, which developed a new method to overcome the problems of Surface Enhanced Raman Spectroscopy (SERS). SERS high sensitivity comes from the interaction of molecules with highly localized and intense fields called plasmons, caused by interaction of light with a metal surface, usually nanostuctured. Research results allow to cut production costs of substrates, and also tackle the lack of reproducibility usually associated to this technique.
