Enhancement of the Electromagnetic Field by Periodic Structures for Raman Spectroscopy Application
Raman spectroscopy is an extremely sensitive and effective method for studying the structure of macromolecules and their changes. The specially designed SERS substrates are one of the ways to enhance Raman signals. Such substrates can significantly increase the sensitivity of optical diagnostics of materials in the ultra-small quantities. It is important for different applications in science, industry and human activity. At present time, the problem of design and optimization of the different substrates for enhance Raman signals remains relevant.
