This book was released on 1996 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here we discuss the preparation and characterization of photopolymerizable, self-assembled monolayers (SAMs) that consist of acid-, hydroxyl-, and methyl-terminated n-alkylthiois containing a diacetylene group (HS(CH 2)10C equivalent C(triple bonds)CC(triples bonds)C(CH2)10X; X=COOH, CH2OH, and CH3, respectively). The acid and hydroxyl surfaces are readily amenable to further synthetic elaboration, while the methyl-terminated SAM results in a clean, low-energy surface. As demonstrated by Fourier transform infrared external reflectance spectroscopy (FTIR-ERS), surface-enhanced Raman spectroscopy (SERS), ellipsometry, UV-vis spectroscopy, and electrochemical methods, all three materials self assemble onto Au surface to form ordered monolayers that can be photopolymerized with UV light. The polymerized SAMs are extremely durable compared to simple n-alkanethiol SAMs. For example, they are stable to electrochemical cycling, thermal excursions to 200 deg C, and exposure to hot base (1:1 mixture of ethanol and 1.0 M aqueous KOH at 100 deg C). All of these conditions completely strip n-alkanethiol SAMs from Au substrates. These high-performance materials are suitable for applications in lubrication, adhesion, corrosion inhibition, and chemical sensing.

Download or read book Surface Functionalization and Applications of Self assembled Monolayers written by Limin Wang and published by . This book was released on 2021* with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Self-assembled monolayers, form a dense assembly of organic molecules on various solid substrates and have caught strong attention due to their large number of potential applications in sensors, biochips, anti-fouling surface, organic electronics, optical devices, etc.. Silane- and thiol-containing molecules represent two classes of the most extensively investigated SAMs. Silane-based monolayers show good stability in their physical and chemical properties which allow them to be further functionalized by different surface chemical reactions or electrochemical oxidation lithography, while the simple and reproducible preparation procedure of thiol-containing SAMs attached to Ag/Au substrates motivates their use, e.g., as analytes in SERS applications. In this thesis, three different potential applications for SAMs were investigated to introduce surface chemical reactions on silane-based SAMs, to utilize surface modification by electrochemical oxidation lithography on OTS monolayers, and finally to investigate the stability of SERS substrates when being immersed into different solvents and buffer solutions utilizing 4-ATP as probe molecules.

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 Optimization and Characterization of Self assembled Monolayer Multilayer Surface enhanced Raman Scattering Substrate for Immuno nanosensors written by Charles Kofi Klutse and published by . This book was released on 2012 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface-enhanced Raman scattering (SERS) is a powerful analytical tool and the recent expansion of substrates for SERS measurement broadens its field of applications, including SERS-based immuno-nanosensing. This dissertation describes the optimization and characterization of self-assembled monolayer (SAM) multilayer SERS substrates for improving performance of different types of substrates. SERS substrates derived from metal film on nanostructures were modified with multiple metal films interspaced with SAM dielectric spacers to achieve multilayered SERS substrates. The fundamental concept of this substrate geometry exploited the cumulative effect of the multiple electromagnetic fields and various properties of SAMs to optimize SERS enhancement of multilayer SERS substrates to about 20-fold compared to conventional substrates.

Available in PDF, EPUB and Kindle. Book excerpt: The in situ investigation of electrochemical interfaces structures at the nanoscale is a key element in the understanding of charge and electron transfer mechanisms e.g. in the fields of energy storage or electrocatalysis. This thesis introduces the implementation of tip-enhanced Raman spectroscopy (TERS) in liquid and in electrochemical conditions enabling the nanoscale analysis of electrified solid/liquid interfaces through the strong and local electric field enhancement at gold or silver scanning tunneling microscopy (STM) probes. The ability of TERS to image inhomogeneities in the coverage density of a self-assembled monolayer (SAM) through a layer of organic solvent on gold was demonstrated. A TERS-inspired analytical tool was also developed, based on a TERS tip used simultaneously as a single-hot spot surface-enhanced Raman spectroscopy (SERS) platform and as a microelectrode (EC tip SERS). The reduction of an electroactive SAM could then be monitored by electrochemical and in situ SERS measurements. In situ electrochemical STM-TERS was also evidenced through the imaging of local variations of the electric field enhancement on peculiar sites of a gold electrode with a lateral resolution lower than 8 nm. Finally TERS also demonstrated to be efficient in investigating the structure of organic layers grafted either by electrochemical reduction or spontaneously. This work is therefore a major advance for the analysis of functionalized surfaces.
