Workers from the ÚCHV with collaboration Department of material research SAV published the article in prestige journal Applied Surface Science (https://www.sciencedirect.com/science/article/pii/S0169433217318044). They studied metal nanocavities (Ni/Ag) structures for the application in surface enhanced Raman spectroscopy. Prepared nanostructured surfaces display excellent enhancement of analytical signal with enhancement factor 1010 and great sensitivity. Potential application area of these surfaces is sensorics.
