Raman spectroscopy (RS) is a modern analytical technique that provides information about molecular vibrations and consequently the structure of the analyzed specimen. The Raman effect is based on inelastic scattering of photons by molecules that are being excited to higher vibrational or rotational states. RS has been broadly used in various research fields ranging from forensic analysis of bodily fluids and food science to biochemistry and solid-state physics. In the last decade, several companies have developed hand-held Raman spectrometers. This has enabled utilization of RS directly in the field for applications, such as forensics, agriculture, and mineralogy.
In 1974, Fleischmann and co-authors reported that Raman spectra of pyridine adsorbed on a rough Ag surface had an unexpectedly high intensity. Inspired by this work, Van Duyne and Jeanmaire investigated the origin of such drastic enhancement of Raman spectra, suggesting that it could be caused by electrochemical interfacial field gradient. Several years later, Van Duyne and Schatz proposed “electromagnetic theory” of the surface-enhanced Raman scattering (SERS) effect. It has been suggested that SERS originated from the intensity anomaly, which occurred when the sum of the dipole induced in the adsorbed molecule was added to its image in the metal, at the limit of zero separation between the two. During the last decade, SERS has been actively developed into a robust tool that enables high sensitivity and specificity in the detection of analytes. These advantages, together with the development of inexpensive and effective SERS substrates, have caused SERS to be broadly used in various research fields, such as biochemistry, cell biology, and catalysis.
RS has been also coupled to scanning probe microscope, which resulted in development of tip-enhanced Raman spectroscopy (TERS), a technique that has nanoscale spatial resolution and single-molecule sensitivity. The substrate generality of TERS has already been utilized to investigate various topics in biology and surface chemistry, such as detecting cytochrome c oxidation in mitochondria, monitoring catalytic reactions, imaging mixed polymer surfaces, and identification of colorants directly in artwork.
This journal issue aims to attract interest of scientists to RS and related spectroscopic techniques. It also aims to demonstrate advantages and the most recent achievements of RS in medicine, agriculture and biochemistry.
