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.

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 excerpt: Recently it has been proposed based on thermal desorption, electron spectroscopy and work function measurements that extremely small pores and cavities in silver films deposited at temperatures below 150K are the location of active sites for surface enhanced Raman scattering. The experiment reported here is an attempt to demonstrate in a more direct way that these cavities are responsible for the observed enhanced Raman scattering. It is shown that by filling these cavities with Xe atoms the enhancement effect on deposited pyridine can be dramatically reduced.
