Highlighting the importance of utilising the polarisation properties of resonance Raman scattering in obtaining molecular information

R-Raman-25_5-F5-sIn resonance Raman scattering (RRS), the amount of structural and chemical information deduced can be increased by analysing the polarisation of the inelastically scattered light, including the degree of molecular aggregation in bio-molecules in their natural environment.

Fourier transform infrared spectroscopic imaging of live cells

IR-25_5-F1-sThere are a number of approaches, and by combining FT-IR imaging methodology with microfluidics devices, the opportunity to study live cells by FT-IR imaging in controlled environments is now possible.

Detection of thiabendazole applied to organic fruit by near infrared surface-enhanced Raman spectroscopy

User Rating: / 3

Raman-25-4-F1-sThiabendazole (TBZ) is a chemical fungicide and parasiticide used to prevent mould, blight and other diseases resulting from long transportation and storage, largely used as an ingredient in waxes applied to the skins of citrus fruits. The authors describe their work using near infrared-surface-enhanced Raman spectroscopy and conventional Ag nanoparticles, which showed that TBZ was found both on organic fruit and at levels higher than regulations allow.
