BACKGROUND Chinese herbal medicine (CHM) is of noteworthy international interest due to its potential impact on healthcare and manifests numerous opportunities for new drug development. However, solid scientific evidence is still lacking regarding the safety, efficacy, and quality of CHM-derived medicines. Success in the modernization and globalization of CHM is heavily dependent on the achieve...

Recent studies of supported vanadium oxide catalysts have revealed that the vanadium oxide component is present as a twodimensional metal oxide overlayer on oxide supports (i.e., A1203, TiO2) (1-9). These surface vanadium oxide species are generally more selective and active than bulk, crystalline V205 for the partial oxidation of hydrocarbons (3, 5, 10, 11). The molecular structures of these s...

This chapter is a review of the application of Raman spectroscopy in characterizing the properties of graphene, both exfoliated and synthesized, and graphene-based materials such as graphene-oxide. Graphene is a 2dimensional honeycomb lattice of sp2-bonded carbon atoms and has received enormous interest because of its host of interesting material properties and technological potentials. Raman s...

Raman spectroscopy is a label-free method of obtaining detailed chemical information about samples. Its compatibility with living tissue makes it an attractive choice for biomedical analysis, yet its translation from a research tool to a clinical tool has been slow, hampered by fundamental Raman scattering issues such as long integration times and limited penetration depth. In this review we de...

Address correspondence to [email protected] ABSTRACT Graphene has many unique properties that make it an ideal material for fundamental studies as well as for potential applications. Here we review recent results on the Raman spectroscopy and imaging of graphene. We show that Raman spectroscopy and imaging can be used as a quick and unambiguous method to determine the number of graphene layers...

Near-infrared Raman spectroscopy has been used for species identification of pure microbial specimens for more than a decade. More recently, this optical method has been extended to the analysis of specimens containing multiple species. In this report, we demonstrate rapid, reagent-free quantitative analysis of a simplified model of oral plaque containing three oral bacteria species, S. mutans,...

The European project FAIR-CT96-5053 concerned the application of the FT-Raman and infrared spectroscopy in food chemistry and quality control. Our research mainly concerned the study of the potential of Raman spectroscopy and the comparison with the results achieved in infrared spectroscopy. The discrimination of virgin olive oil from other edible oils, and the detection and quantification of v...

This paper introduces Raman spectroscopy and discusses various scenarios where it might be applied to in situ planetary missions. We demonstrate the extensive capabilities of Raman spectroscopy for planetary investigations and argue that this technique is essential for future planetary missions.

Raman spectroscopy is currently a part of the instrumentation suite of the ESA ExoMars mission for the remote detection of life signatures in the Martian surface and subsurface. Terrestrial analogues of Martian sites have been identified and the biogeological modifications incurred as a result of extremophilic activity have been studied. Analytical instrumentation protocols for the unequivocal ...
