A Comparison of Phycocyanins from Three Different Species of Cyanobaci’eria Employing Resonance-enhanced Coherent Anti-stokes Raman Spectroscopy
نویسندگان
چکیده
Resonance-enhanced coherent anti-Stokes Raman spectra are recorded for monomers and trimers of phycocyanin from three different cyanobacteria: Westieflopsis prolijica, Mastigoc/adu.s faminosus and Spirulina platensis. It is shown that upon aggregation from monomer to trimer the electronic structures of both the a84 and 684 chromophores are changed. The spectra of the trimers originating from S. platensis and M. laminosus are very similar to each other, but distinctly different from the spectrum of W. prolifica.

Biosensing Based on Surface-Enhanced Raman Spectroscopy by Using Metal Nanoparticles
Surface-enhanced Raman spectroscopy (SERS) is a promising tool in the analytical science because it provides good selectivity and sensitivity without the labeling process required by fluorescence detection. This technique consists of locating the target analyte on nanometer range of roughed Au-nanoparticles. The presence of the metal nanoparticles provides a tremendous enhancement to the result...
متن کاملRaman spectroscopy in chemical bioanalysis.
Advances in instrumentation are making Raman spectroscopy the tool of choice for an increasing number of (bio)chemical applications. Raman is an interesting option for several reasons, including the sensitivity to small structural changes, non-invasive sampling capability, minimal sample preparation, and high spatial resolution in the case of Raman micro-spectroscopy. Herein we discuss the most...
متن کاملCoherent Anti-Stokes Raman Spectroscopy (CARS) Applied in Combustion Probing
\Ye have applied Coherent Anti-Stokes Raman Spectroscopy (CARS) for monitoring of a variety of important molecules in combustion media. A survey of different CARS techniques ranging from simple, scanning measurements of major species like N , to single-pulse, broad-band arraydetector registration of less abundant species is made. The CARS, BOXCARS and folded BOXCARS approaches were used observi...

Width-increased dual-pump enhanced coherent anti-Stokes Raman spectroscopy (WIDECARS) is a technique that is capable of simultaneously measuring temperature and species mole fractions of N(2), O(2), H(2), C(2)H(4), CO, and CO(2). WIDECARS is designed for measurements of all the major species (except water) in supersonic combustion flows fueled with hydrogen and hydrogen/ethylene mixtures. The t...
متن کاملResonance-enhanced coherent anti-Stokes Raman scattering in C2
2014 We have obtained resonance-enhanced Coherent Anti-Stokes Raman Scattering (CARS) spectra of the C2 radical formed in a microwave discharge and in an acetylene welding torch. Electronic resonance enhancement was obtained in the Swan system. In order to prepare this work, Swan band emission spectra of C2 had been recorded and assigned using Fourier-transform spectroscopy; this enabled us to ...
