“…The effect of the substrate type on the Raman scattering intensity was formally treated, for the first time, by Greenler and Slager before even the SERS phenomenon was predicted. Greenler model was modified, improved, and developed recently by Liu and Zhao to the case of SERS from tilted nanorods deposited on flat substrates.…”

Nano-sculptured thin films (nSTFs) is a group of meterials prepared by the oblique or the glancing angle deposition technique. They take the form of rods having different shapes such as nanocolumns, nanoscrews, nanozigzags and many other nanoshapes. Their potential for biosensing is highlighted in this review particularly the metallic ones due to their remarkable plasmonic properties. The techniques that have been shown so far to be of high potential are: extended surface plasmon resonance (SPR), localised SPR, surface enhanced flourescence (SEF) and Raman scattering (SERS). The use of metal nSTFs in SPR biosensors with Kretschmann-Raether configuration enhances both the angular and the spectral sensitivities due to the porosity and adds more degrees of freedom in designing evanescent waves based techniques. The metallic nSTFs, exhibit remarkable localised plasmonic properties that make them a promising substrate for enhanced spectroscopies. Their long term stability in water environment makes them suitable candidates for biosensing in water as it is already demonstrated for several water pollutants. The influences of the nanostructures' size, topology, the substrate features, and the preparation conditions on the enhancement of SEF and SERS are highlighted with emphases on the unresolved issues and future trends.

“…For Raman scattering these considerations apply to both the incident and scattered fields and can be used to optimize the experimental design, and determine vibrational symmetries and molecular orientations, which I will discuss in subsequent sections. Greenler (9) was the first to consider Raman scattering by a molecule adsorbed on a planar surface as a problem in classical electrodynamics. (10) His model is simple.…”

“…For the case of a molecule directly on a metal/vacuum interface, intensities and angular dependencies have been ex- plicitly calculated by several researchers, including Greenler and Slager, 40 Moskovits 41 and Campion. 42 With some modifications, we can use these methods to compare Raman intensities for a standard 90 deg scattering geometry to the case of clusters distributed in a matrix at a finite distance from an Ag film.…”

The structures and coalescence behavior of size-selected, matrix-isolated silicon clusters have been studied using surface-plasmon-polariton ͑SPP͒ enhanced Raman spectroscopy. The cluster ions were produced in a laser vaporization source, mass selected then deposited into a co-condensed matrix of Ar, Kr or N 2 on a liquid He cooled substrate. Raman spectra from monodisperse samples of the smaller clusters studied, Si 4 , Si 6 and Si 7 , show sharp, well-resolved, vibrations which are in good agreement with predictions based on ab initio calculations. From these comparisons we confirm that Si 4 is a planar rhombus, and assign Si 6 as a distorted octahedron and Si 7 as a pentagonal bypyramid. Si 5 depositions down to 5 eV did not reveal a measurable Raman spectrum under our experimental conditions. Evidence for cluster-cluster aggregation ͑or fragmentation͒ was observed under some conditions, even for a ''magic number'' cluster such as Si 6 . The spectra of the aggregated small clusters were identical to those observed for directly deposited larger cluster ''bands,'' such as Si [25][26][27][28][29][30][31][32][33][34][35] . The Raman spectra of the aggregated clusters bear some similarity to those of bulk amorphous silicon. Cluster-deposited thin films were prepared by sublimating the matrix material. Even under these ''soft landing'' conditions, changes in the Raman spectrum are observed with the thin films showing even greater similarity to amorphous silicon.
