Tailor-designed Au/SiO(2) core/shell nanoparticles are employed to enhance the efficiency of fluorescence resonance energy transfer based on quantum dots and R-phycoerythrin in solution.

The molar extinction coefficient for phycoerythrobilin (l a) was calculated by two independent methods. It is different from that of the cleaved chromophore, phycobiliviolin (2). By unfolding with urea or tryptic digestion, the chromophore absorption of C-phycoerythrin (PE) was determined free of any protein influence. The chromophore content of PE from various Cyanobacteria was determined with...

I am interested in understanding how, and in what ways, the taxonomic composition of the phytoplankton affects ecosystem-level processes in the sea. I am particularly interested in the relationship between the optical environment and the distribution of phytoplankton with different light harvesting pigments. To this end, I have been working in collaboration with experts in remote sensing and oc...

Abstract Phycobiliproteins, including phycoerythrins, are a group of water-soluble pigments produced by microalgae that show potential for being used as natural colourants. The replacement synthetic compounds with colourants obtained from renewable resources is gaining increased interest in the beverages industry. aim present study was to generate and characterise phycoerythrin-rich extract mic...

Abstract Phycobiliproteins are pigments with uses in pharmacology, cosmetics, foods, and as fluorescent probes biochemistry. Cryptophyte microalgae one possible source of phycobiliproteins well other molecules such omega-3 fatty acids. The use cryptophytes biotechnology is currently very limited especially the potential freshwater species poorly documented. For commercial production, it importa...

An extensive study o f the chiroptical properties o f C-phycoerythrin and the aand ^-subunits in the spectral region from 700 200 nm is presented. Based on the VIS-circular dichroism inherently chiral conformations are proposed for the co­ valently linked chromophores. By means o f mean residue ellipticities and the experimental circular dichroism spectra in the region o f the n -* n* peptide t...
