Surface-Enhanced Raman Spectroscopy in Modern Chemical Analysis: Achievements and Prospects

Abstract

The report will consider the current state, achievements and prospects of Surface-Enhanced Raman Spectroscopy (SERS) in chemical analysis. The main advantages (non-destructiveness, high sensitivity and selectivity, rapid analysis, minimal sample preparation) and disadvantages of this method that must be overcome to move from fundamental problems and solutions to practical application will be noted.
The capabilities of SERS in creating highly sensitive sensors for detecting various substances (creation of new substrates, methods for increasing sensitivity and selectivity) will be shown, new areas of SERS application will be demonstrated, such as non-destructive testing of biomaterials and new diagnostic methods, development of portable and inexpensive devices based on SERS for widespread use in the field.
Particular attention will be paid to new approaches to creating indicator systems that significantly expand the analytical capabilities of the method, as well as allowing an increase in the number of analyzed compounds. Examples of the use of SERS spectroscopy in the most important areas of science and technology, which require qualitative and quantitative chemical analysis of complex samples, will be given, and the prospects of SERS sensor systems in the analysis of biological samples and samples of environmental monitoring will be discussed within the framework of this report.
The work was carried out with the financial support of the Russian Science Foundation 23-13-00276.
