Fundamentals and Applications of Surface Enhanced Raman Spectroscopy

Abstract

As an advanced approach to Raman spectroscopy, Surface enhanced Raman spectroscopy (SERS) is known to be a powerful tool in detecting molecules at very low concentration level. The enhancement in Raman signals of probe molecules can be achieved by using the interaction between probe molecules and SERS active substrates. The fundamental concepts related to SERS study have been discussed in the present chapter. Electromagnetic and chemical interactions for improved Raman signals have been discussed. Recent advancement in SERS study with different metals and semiconducting active substrates have been provided as examples for the detection of organic molecules. © 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
