Download or read book Surface Enhanced Raman Spectroscopy for Biophysical Applications written by Claudia Fasolato and published by Springer. This book was released on 2018-12-05 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book explores the phenomenon of surface-enhanced Raman scattering (SERS), the huge amplification of Raman signal from molecules in the proximity of a metallic nanostructured surface, allowing readers to gain an in-depth understanding of the mechanisms affecting the spectroscopic response of SERS-active systems for effective applications. SERS spectroscopy is an ultrasensitive analytical technique with great potential for applications in the field of biophysics and nanomedicine. As examples, the author presents the design of nanocolloid-based SERS-active substrates for molecular sensing and of a folate-based SERS-active nanosensor capable of selectively interacting with cancer cells, enabling cancer diagnostics and therapy at the single-cell level. The author also suggests novel paths for the systematization of the SERS nanosystem design and experimental protocols to maximize sensitivity and reproducibility, which is essential when real-world biomedical applications are the goal of the study. With a combined approach, both fundamental and applied, and a detailed analysis of the state of the art, this book provides a valuable overview both for students new to SERS spectroscopy and for experts in the field.

Download or read book Investigation Into the Use of Surface enhanced Raman Spectroscopy SERS for Organic Dye Analysis written by and published by . This book was released on 2015 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: In art conservation, color is essential to understanding a society's culture and history-as an indicator of beauty, status, religion, and more-but has a tendency to fade and diminish over time. Analytical techniques, particularly that of pigment identification, can reveal the artifact's original color and appearance and give new insights to an artist's intentions, techniques, date of creation, and more. However, most identification procedures are invasive and destroy the samples in the process. Surface-enhanced Raman spectroscopy (SERS) has recently been identified as a technique that is minimally invasive and also solves the issue of fluorescence that is found in many other techniques. In this paper, a specific SERS procedure has been developed for the identification of yellow organic dyes from 18th century Japanese Woodblock prints. Several SERS spectra of nine dyes both in solution and applied on artist paper have also been documented in hopes of assisting with pigment identification in the future.

Download or read book Surface Enhanced Resonance Raman Spectroscopy of Dyes written by and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Herein analysis of dye molecules has been carried out by means of surface enhanced Raman spectroscopy (SERS) and/or surface enhanced resonance Raman spectroscopy (SERRS) using citrate- and/or borohydride-reduced silver colloids employing laser exciting wavelengths equal to 514.5 and/or 632.8 nm. SERS and/or SERRS spectra are reported using, as model system probes, eight dye molecules which belong to several distinct chemical structural classes. Experimental protocols were developed and subsequently modified, as required, for each dye molecule examined. Vibrational spectroscopic profiles were obtained, where possible, with respect to concentration and pH dependence. SERS and/or SERRS vibrational bands provided unique fingerprint spectra for each dye molecule. In an attempt to develop novel applications of SERRS the technique has been used, in a kinetic investigation, to monitor and analyse the synthesis of the dye indigo carmine from indigo using a silver sol as the SERRS substrate/medium. In another study it was possible to differentiate between two structurally similar anthraquinones, alizarin and purpurin, using SERRS. It was also possible to demonstrate the existence of multiple molecular species of certain dye molecules, as a function of pH e.g. nuclear fast red, metanil yellow, purpurin and alizarin. For some dye molecules e.g. alcian blue it was possible to combine the linear regions of normal (non-resonance/non-enhanced) Raman and SERS/SERRS plots, thereby extending the dynamic range available for semi-quantitative analysis. The sensitivity of the SERS/SERRS technique for semi-quantitative trace analysis of eight dye molecules has been successfully demonstrated.
Download or read book Raman Spectroscopy An Intensity Approach written by Guozhen Wu and published by World Scientific. This book was released on 2016-08-18 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the highlights of our work on the bond polarizability approach to the intensity analysis. The topics covered include surface enhanced Raman scattering, Raman excited virtual states and Raman optical activity (ROA). The first chapter briefly introduces the Raman effect in a succinct but clear way. Chapter 2 deals with the normal mode analysis. This is a basic tool for our work. Chapter 3 introduces our proposed algorithm for the Raman intensity analysis. Chapter 4 heavily introduces the physical picture of Raman virtual states. Chapter 5 offers details so that the readers can have a comprehensive idea of Raman virtual states. Chapter 6 demonstrates how this bond polarizability algorithm is extended to ROA intensity analysis. Chapters 7 and 8 offer details on ROA, showing many findings on ROA mechanism that were not known or neglected before. Chapter 9 introduces our proposed classical treatment on ROA which, as combined with the results from the bond polarizability analysis, leads to a comprehensive physical picture for the Raman effect. In particular, this classical treatment unifies ROA and VCD (vibrational circular dichroism) on equal footing. In each section, Comments summarize the key ideas and their evaluation. This will help the readers to capture the core ideas of the presentations.
