The photophysical properties of 7-(diethylamino) coumarin-3-carboxylic acid (7-DCCA) were studied in cyclodextrins (α, β, γ,-CDs), different neat solvents and solvent mixtures by using steady state absorption, emission and time-resolved fluorescence spectroscopy. We have observed that with gradual increase in concentration

Amyloid beta-protein (Abeta) has been reported to interact with a variety of lipid species, although the thermodynamic driving force remains unclear. We investigated the binding of Abetas labeled with the dye diethylaminocoumarin (DAC-Abetas) to lipid bilayers under various conditions. DAC-Abeta-(1-40)
