This book reflects the dramatic increase in the number of Raman spectrometers being sold to and used by non-expert practitioners. It contains coverage of Resonance Raman and SERS, two hot areas of Raman, in a form suitable for the non-expert. Builds Raman theory up in stages without overloading the reader with complex theory. Coming to the surface. For Raman spectroscopy to reach into the realm of single molecule detection required the accidental discovery, in , that molecules of pyridine on a rough silver surface gave an unexpectedly strong Raman scattering signal.

Development of a Raman Spectrometer to study surface enhanced Raman Scattering by Nandita Biswas Download PDF EPUB FB2

Surface-enhanced Raman spectroscopy or surface-enhanced Raman scattering (SERS) is a surface-sensitive technique that enhances Raman scattering by molecules adsorbed on rough metal surfaces or by nanostructures such as plasmonic-magnetic silica nanotubes. The enhancement factor can be as much as 10 10 to 10 11, which means the technique may.

This article reviews Raman instrumentation, with a special focus on the use of mobile and portable instruments, recent developments in the field of. The steady and fast development of surface and interfacial science have set up innovative openings for new diagnostic probes for analytical characterization of the adsorbates and determination of the microscopic structure of surfaces and interfaces.

Regrettably Raman spectroscopy, being a weak scattering surface phenomenon, had seized no part in it, until the Cited by: 1.

A similar effect to the surface-plasmon-resonance effect like the used on Surface Enhanced Raman Scattering (SERS) [23] is shown in Fig. 9, which. Surface-enhanced Raman scattering (SERS) spectroscopy [2(a),(b)], first reported by Jeanmaire and Van Duyne [2(c)] and Albrecht and Creighton [2(d)], yields stronger enhancement of cross section by several orders of magnitude (up to 10 6).

SERS offers the possibility of overcoming many of the problems in conventional Raman spectroscopy. Raman spectroscopy has been used to study the interactions of the vibrational energies of atoms or groups of atoms within molecules.

The Raman effect is produced through the exchange of energy between incident photons and the vibrational energy levels of the scattering is the inelastic scattering of laser light impinged onto the sample and is scattered.

Surface-enhanced Raman scattering (SERS) has become a powerful tool in chemical, material and life sciences, owing to its intrinsic features (i.e., fingerprint recognition capabilities and high sensitivity) and to the technological advancements that have lowered the cost of the instruments and improved their sensitivity and by: The surface enhanced Raman scattering (SERS) of a number of species and strains of bacteria obtained on novel gold nanoparticle (∼80 nm) covered SiO2 substrates excited at nm is reported.

Raman cross-section enhancements of > per bacterium are found for both Gram-positive and Gram-negative bacteria on these SERS active substrates. The SERS spectra of. The use of Surface-Enhanced Raman Scattering (SERS) in sensing applications has recently received a lot of attention.

Strong enhancements of Raman signals for molecules adsorbed on nanostructures made of noble metals such as silver and gold dramatically increase Raman scattering cross by: Surface-enhanced Raman scattering (SERS) and tip-enhanced Raman scattering (TERS) are fast, convenient, and non-destructive molecular detection techniques, which provide a practical method for studying interfacial reactions with high resolution and accuracy.

Both techniques are able to provide quantitative and qualitative information on the chemical properties, Author: Kun Zhang, Zongwei Xu, Andreas Rosenkranz, Ying Song, Tao Xue, Fengzhou Fang. Abstract. Surface-enhanced Raman spectroscopy (SERS) is a spectroscopic technique that simultaneously combines fingerprint recognition capabilities, typical of vibrational spectroscopies, and very high sensitivity (down to single molecule), owing to the enhancement provided by plasmonic by: 4.

Surface- and tip-enhanced Raman spectroscopy (SERS and TERS) techniques exhibit highly localized chemical sensitivity, making them ideal for studying chemical reactions, including processes at catalytic surfaces. Catalyst structures, adsorbates, and reaction intermediates can be observed in low quantities at hot spots where electromagnetic fields are the strongest.

Surface Enhanced Raman Scattering (SERS) has been widely praised for its extreme sensitivity but has not so far been put to use in routine analytical applications, with the accessible scale of Author: Gwennhaël Brackx, Damien Guinoiseau, Ludovic Duponchel, Alexandre Gélabert, Victoria Reichel, Samia.

Therefore the whole set-up could easily be brought to the water point to provide readings on the spot. Nanowires (NWs) are filamentary crystals with diameters of tens of nanometers and lengths of few microns.

Semiconductor NWs have recently attracted a great interest, because they are emerging as building blocks for novel nanoscale devices. Since physical properties are size dependent, NWs display novel properties with respect to their bulk counterparts.
