ABSTRACT
As a hallmark technique in nanosciences, SERS matured with the advent of tools for nanofabrication and sub-wavelength optical measurements. This rapid development of SERS has been reviewed by several authors who focused on specific aspects of the technique, including SERS substrates (metallic nanostructures that support the effect) [1], SERS applications in analytical [2], biological [3] and environmental chemistry [4], SERS theory [5-7], and other modern technologies derived from SERS, such as tipenhanced Raman scattering (TERS) [8-10].
