Book Synopsis A Chemical Free Approach for Increasing the Biochemical Surface-enhanced Raman Spectroscopy (SERS)-based Sensing Capabilities of Colloidal Silver Nanoparticles by : Kevin Michael Dorney
Download or read book A Chemical Free Approach for Increasing the Biochemical Surface-enhanced Raman Spectroscopy (SERS)-based Sensing Capabilities of Colloidal Silver Nanoparticles written by Kevin Michael Dorney and published by . This book was released on 2014 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: The unique optoelectronic properties of silver nanoparticles (AgNPs) have led to their explosive use in a multitude of both research and industrial settings in recent years. Localized surface plasmon resonance (LSPR) exhibited by AgNPs has been exploited extensively as a nano-scale probe in a variety of spectroscopic detection modalities, particularly in surface-enhanced Raman spectroscopy (SERS). The SERS effect is highly dependent upon the LSPR interaction with optical laser frequencies, thus optimization of LSPR via specific control of AgNP dimensionality and composition of the surrounding medium is vital for increasing the efficacy of SERS-based nano-sensing. This work aimed to augment LSPR of AgNPs by applying the chemical free technique of tangential flow filtration (TFF) to a Creighton colloid of spherical AgNPs and specifically tailoring their size-distribution, concentration, and purity. First, a large batch of Creighton AgNPs (1-100 nm in diameter) were size-selected (20 nm and 12 nm in average diameter), concentrated, and purified via a three-step TFF procedure and characterized for effectiveness as SERS substrates in pre-resonance, resonance, and single-molecule resonance conditions for a Raman reporter, rhodamine 6G. The 20 nm AgNPs were found to have the highest surface enhancement factors (SEFs) in pre-resonance and single molecule resonance (SEFS of 2.1 x 10^6 and 2.5 x 10^10), while the 12 nm AgNPs yielded the highest SEFs in resonant conditions (2.0 x 10^6). The TFF procedure was then introduced to a diverse class of undergraduate and graduate students in an Experimental Nanomaterials and Nanoscience course to demonstrate the versatility of the proposed method for both gold nanoparticles and AgNPs, as well as the ease of applicability for use in different research disciplines and settings. Lastly, the 20 nm TFF-obtained AgNPs were employed for the sub-nanomolar biochemical detection of a potent apoptotic metabolite, chelerythrine (CET), in human lens epithelial cell extracts. The TFF-fractionated AgNP colloid allowed for quantification of CET content within several cell compartments via a reproducible calibration curve extending over five orders of magnitude (10^-5 to 10^-10 M in CET concentration). The results of these aims offer strong evidence that TFF can be 1) utilized to yield SERS substrates capable of extending detection limits and increasing spectral signals, 2) easily adapted for a variety of nanoparticle colloids as well as research and industrial settings, and 3) employed to obtain AgNPs that facilitate trace biochemical SERS-based detection even in extensive biological matrices.

Book Synopsis Application of SERS for Nanomaterials by : Ronald Birke
Download or read book Application of SERS for Nanomaterials written by Ronald Birke and published by . This book was released on 2022 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Special Issue of “Applications of SERS” for Nanomaterials is a collection of articles which is representative of much of the current research being undertaken in the field of Surface-Enhanced Raman Scattering (SERS) spectroscopy. SERS is a fascinating, multidisciplinary field of scientific study which combines elements from chemistry, physics, material science, and engineering. Essentially, SERS is a molecular spectroscopy technique by which a measurable Raman signal for molecules on metal and semiconductor surfaces is generated through the interaction of laser light, absorbed molecules, and structured nanomaterial surfaces. This Special Issue contains an article regarding the fabrication of metal nanostructured Ag-Cu chips for SERS chemical analysis and ] the electromagnetic properties of Ag, Au, and Al nano-tips for use in the SERS imaging technique for tip-enhanced Raman Scattering (TERS). In another article, SERS spectra were simulated using density Functional Theory (DFT/TD-DFT) for the N3 dye molecule on a TiO2 nanocluster, which can be compared to experimental SERS spectra found in studies of Dye-Sensitized Solar Cells (DSSCs). In two other articles, the SERS photoinduced charge-transfer mechanism was studied experimentally in wide-bandgap semiconductors regarding molecules on ZrO2 and a composite system with molecules that linked Au nanorods and a CuO2 shell. An example of the use of SERS in solid-state physics is shown in an article which examined the effect of oxygen vacancy defects in MO3 on the SERS mechanism. Finally, this Special Issue contains two noteworthy examples of SERS applications for biochemical and chemical analysis. One paper addresses the detection of the COVID-19 coronavirus SARS-CoV-2 using SERS, and the other examines a SERS assay of the notorious herbicide glyphosate. In these papers, nanomaterials all served as the enhancing substrate, while some acted as the physical-chemical system which was being investigated.

Download or read book Ag Nanostructures Application in Surface Enhanced Raman Spectroscopy written by Alfred Maingi and published by LAP Lambert Academic Publishing. This book was released on 2011-08 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent contamination of food by the use of melamine has led to huge economic losses in the food industry. Food and drug administration (FDA) currently uses methods that are laborious and time consuming. As a consequence scientists have been grappling with development of methods that are more efficient and cost effective for trace analysis of various food adulterates. One such method is the use of silver nanostructures in the presence of Surface Enhanced Raman spectroscopy that are capable of generating high enhancement of the signals, leading to low detection of the signals from the analyte. In the book, a literature review of the various synthesis methods, purification of the end products, assembly of nanostructures on glass templates as well as characterization of silver nanowires/nanoparticles and their potential use in Surface Enhanced Raman Spectroscopy is suggested.
