Book Synopsis SOLUTION PROCESSABLE SURFACE ENHANCED RAMAN SPECTROSCOPY (SERS) SUBSTRATE by : Narayan Sharma
Download or read book SOLUTION PROCESSABLE SURFACE ENHANCED RAMAN SPECTROSCOPY (SERS) SUBSTRATE written by Narayan Sharma and published by . This book was released on 2015 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface Enhanced Raman Spectroscopy is a powerful analytical tool to obtain information on molecular composition. This technique has advanced greatly since its discovery, allowing Raman spectroscopic analysis down to the detection of single molecule. The heart of SERS performance lies on the choice and fabrication of SERS substrate. The most investigated metals for SERS substrates are Au and Ag. Unfortunately, the fabrication of such devises poses a significant challenge due to an expensive deposition technology including, vapor deposition, electron-beam lithography, focused ion-beam lithography, and nano-transfer printing. Herein, we report a simple and low-cost solution processing method to fabricate SERS substrates. Au nanoparticles and Au/CdS core/shell nanoparticles were synthesized and their solutions deposited on glass plates in the form of nanoparticle films. Although the enhancement of Raman signal due to Ag nanoparticle substrates is greater than that of Au, the high stability and a wide variety of fabrication methods makes Au nanoparticles more favorable candidates for SERS substrates. The performance of the SERS substrates fabricated using this method was found to be comparable with the commercially available substrates.
Book Synopsis Improving Analytical Utility of Surface Enhanced Raman Spectroscopy Through Unique Lithographic Substrate Development by : Sabrina Marie Wells
Download or read book Improving Analytical Utility of Surface Enhanced Raman Spectroscopy Through Unique Lithographic Substrate Development written by Sabrina Marie Wells and published by . This book was released on 2012 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface enhanced Raman spectroscopy (SERS) has the potential to be a useful analytical technique due to large signal enhancements. Unfortunately, SERS has several drawbacks, including a lack of reproducibility, which inhibits it from being a practical option. These large signals often arise from "hot spots" of extremely high enhancement on nanofeatured metallic substrates, the most common being comprised of aggregated silver colloid. It is difficult to reproducibly create these hot spots due to the randomness of the colloid substrates. However, through controlled substrate fabrication, many problems associated with SERS analysis can be overcome. Electron beam lithography (EBL) combined with reactive-ion etching (RIE) was used to fabricate a wide variety of aggregate-like structures that allow for methodically surveying the system to determine if areas of high enhancement are present. Any well performing areas were then recreated consistently to produce areas of similar enhancement. While the aforementioned "combinatorial" approach has its advantages, simple structures are often easier to fabricate and theoretically model. As such, a single structure consisting of a metal disc on a silicon pillar was created. A variety of tests were performed on these structures to determine the overall utility of the simple pillar system. The system was found to possess extremely high enhancement, making it an ideal system to both theoretically model and test experimentally. The system also has strong enough overall signal to allow for potential analytical implications. Studies were also conducted to determine the feasibility of using a strong enhancing silicon nanopillar system to make analytical measurements without a metal surface present. A special fabrication process using EBL and RIE was used to created tall, high aspect ratio pillars of known diameters. These nanopillars were then observed to exhibit special optical properties not seen in bulk silicon. Aside from modest Raman enhancement, these structures also demonstrated the ability to enhance the signal of specific analytes similar to SERS. Surface enhanced fluorescence (SEF) was also observed for different analytes, allowing for a variety of potential analytical areas.
Book Synopsis An Overview of Anodic Oxides Derived Advanced Nanocomposites Substrate for Surface Enhance Raman Spectroscopy by : Marta Michalska-Domanska
Download or read book An Overview of Anodic Oxides Derived Advanced Nanocomposites Substrate for Surface Enhance Raman Spectroscopy written by Marta Michalska-Domanska and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface-enhanced Raman spectroscopy (SERS) is an analytical technique, which allows to identify traces of chemical or biological substances in many field, like pharmaceutical and food industries, homeland security, nanosensors, or environmental protection. The analytes are identified based on their vibrational spectra, unique for a given compound. The advantage of SERS is effective qualitative analysis of trace amounts of analyte, but the disadvantages are stability of substrate and repeatability of measurements. The challenge is to improve SERS substrates to minimize these drawbacks. Nowadays high-precision electron beam lithography or focused ion beam is used in SERS substrate fabrication, which is impractical for large-scale production. In recent years, researchers,Äô attention has focused on porous anodic oxides, with inexpensive and scalable production method, as potential materials for SERS substrates. This chapter will discuss the progress of anodic oxides used as a SERS substrate, and the brief description of conventional SERS substrate fabrication methods will be presented.

This book was released on 2012-02-24 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ten years after coming into force of the Stockholm Convention on Persistent Organic Pollutants (POPs), a wide range of organic chemicals (industrial formulations, plant protection products, pharmaceuticals and personal care products, etc.) still poses the highest priority environmental hazard. The broadening of knowledge of organic pollutants (OPs) environmental fate and effects, as well as the decontamination techniques, is accompanied by an increase in significance of certain pollution sources (e.g. sewage sludge and dredged sediments application, textile industry), associated with a potential generation of new dangers for humans and natural ecosystems. The present book addresses these aspects, especially in the light of Organic Pollutants risk assessment as well as the practical application of novel analytical methods and techniques for removing OPs from the environment. Providing analytical and environmental update, this contribution can be particularly valuable for engineers and environmental scientists.
