This chapter presents a self-contained introduction to Raman spectroscopy and related optical techniques, which is more general than what is actually needed for surface-enhanced Raman spectroscopy (SERS) in several aspects, but covers the essential concepts and provides a unifying view of the basic material. strongly enhanced Raman signals were verified for many different molecules [4] which had been attached to various ‘rough’ metal surfaces, and the effect was named ‘surface-enhanced Raman scattering (SERS)’. Questions (153) Publications (32,714) Currently, cancer is a global health problem and various techniques are used for detection, however, the final outcome is defined by the pathological study of a biopsy taken. This can substantially improve the limit of detection and allows very small concentration of substances to be detected and identified. Surface‐enhanced Raman scattering (SERS) was discovered in the mid‐1970s, by which the intrinsically low detection sensitivity of Raman spectroscopy is no longer a fatal disadvantage for this analytical tool. Applications; References; Figure 1: A typical representation of measurements taken using Raman Spectroscopy Figure 2: Jablonski diagrams depicting the Stokes and Anti-Stokes shifts associated with Raman scattering. However, generally substrates based on metals such as Ag, Au an … A tip-enhanced Raman spectroscopy (TERS) based on plasmonic lens (PL) excitation is proposed in this work. By contrast, surface-enhanced Raman spectroscopy (SERS), utilizes surface plasmons to enhance Raman scattering by several orders of magnitude, without requiring different equipment than traditional Raman spectroscopy. Surface-enhanced Raman scattering (SERS) is a powerful spectroscopy technique that can provide non-destructive and ultra-sensitive characterization down to single molecular level, comparable to single-molecule fluorescence spectroscopy. Surface-enhanced Raman spectroscopy (SERS) is an emerging technique for the chemical analysis. The focusing performance of the PL is calculated via finite-difference time-domain (FDTD) simulation and experimentally detected by a scattering-type scanning near-field optical microscope. 1,2,* 1. Surface-enhanced Raman spectroscopy (SERS) is a powerful spectroscopy technique to detect and characterize molecules at a very low concentration level. Abstract: We report a novel on-chip approach for surface-enhanced Raman spectroscopy (SERS) using a plasmonic slot waveguide. Surface-enhanced Raman spectroscopy (SERS) is a powerful tool for sensing, which can detect a broad range of chemical and biological analytes at the single-molecule level. Raman spectroscopy provides a “chemical fingerprint” as it relies on loss (Stokes) or gain (anti-Stokes) in energy of an inelastically scattered photon due to a molecular vibrational event. Surface enhanced Raman scattering (SERS) is a technique which offers orders of magnitude increases in Raman intensity, overcoming the traditional drawback of Raman scattering – its inherent weakness. Introduction. Surface-Enhanced Raman Spectroscopy (SERS) SERS is a phenomenon caused by interacting a laser beam with molecules adsorbed on certain surfaces, such as silver or gold, causing an enhancement of 5-6 orders of magnitude in Raman signal. For an overview see [5, 6]. Patients and methods: We synthesized monodisperse gold nanoparticles as SERS-enhanced substrates and analyzed preoperative plasma samples of patients who underwent RP. REPORT SUMMARY; TABLE OF CONTENTS; The Surface Enhanced Raman Spectroscopy (SERS) market was valued at XX.0 Million US$ in 2018 and is projected to reach XX.0 Million US$ by 2026, at a CAGR (Compound Annual Growth Rate) of 6.5% during the forecast period. Since 2000, there has been an explosion of activity in the field of plasmon-enhanced Raman spectroscopy (PERS), including surface-enhanced Raman spectroscopy (SERS), tip-enhanced Raman spectroscopy (TERS) and shell-isolated nanoparticle-enhanced Raman spectroscopy (SHINERS).

Publisher Summary. Objective: The objective of this study was to evaluate the performance of surface-enhanced Raman spectroscopy (SERS) in the prediction of early biochemical recurrence after radical prostatectomy (RP). Surface-enhanced Raman spectroscopy (SERS), as a surface-sensitive Raman technique that enables significant enhancement of Raman signals of adsorbed molecules on an engineered surface, has been considered as a promising technique to overcome the low sensitivity of traditional Raman spectroscopy. Surface‐enhanced Raman scattering (SERS) has become a mature vibrational spectroscopic technique during the last decades and the number of applications in the chemical, material, and in particular life sciences is rapidly increasing. The two-dimensional (2D) semi-conductor layered material, tin diselenide (SnSe 2), is used as a new substrate for enhancing the Raman signals of adsorbed molecules. An appropriate method is the surface-enhanced Raman spectroscopy (SERS), which provides a large amplification of Raman signals when the probed molecule is adsorbed on a nanosized metallic surface. With the advantages of excellent sensitivity and significant enhancement to identify the target, SERS has become a promising alternative method for PCBs analysis. The Raman signal is excited via free-space excitation and is collected by the waveguide.
