Nanotextured surfaces for surface enhanced Raman spectroscopy and sensors

By Armandas Balcytis, Juodkazyte, Seniutinas, Li, Niaura and Juodkazis


Nanotextured surfaces which have surface features spanning 10-100 nm in length and height scales are among the most promising for surface enhanced Raman scattering/spectroscopy (SERS). Randomness of the feature sizes and surface morphology of such sensors brings an added benefit of spectrally broadband action and, consequently, augmented SERS intensity. Surfaces which are most promising for high sensitivity yet cost efficient for large scale production are overviewed with black CuO, which is made by chemical oxidation of Cu foil, as a representative example. Application potential and challenges to establishing quantitative SERS measurements are outlined
