Identifying Oxide and CaS Non-Metallic Inclusions in Steel with Raman Spectroscopy

Metallic nanorods synthesis and application in surface enhanced Raman spectroscopy

Metallic nanorods synthesized by oblique angle deposition on glass substrate are utilized as nano-scale structures that can be coated with SERS active metal to allow for excitation of surface plasmons. The synthesized nanorods have an average length of ~500-600 nm and are randomly distributed on the substrate. The SERS studies with Near-IR excitation at 785 nm show significant enhancement with ...

use of raman spectroscopy to decrease time for identifying the species of candida growth in cultures

background: the objective of this study is to establish raman signatures from pure cultures of different candida species using raman spectroscopy (rs) and use these signatures for rapid identification of unknown candida species. methods: pure cultures of five candida species were evaluated using rs to build a limited signature library. ‘raman processing’ (rp) software was used for principal com...

Polarized surface-enhanced Raman spectroscopy on coupled metallic nanowires.

Regular-shaped metal nanocrystals and their ensembles can serve as ideal substrates for studying surface-enhanced Raman scattering (SERS). We synthesized well-defined silver nanowires for a systematic study of SERS signal with respect to polarization and structural ordering. The observed dependence on polarization direction confirms prior theoretical predictions that large electromagnetic (EM) ...
