Fluorescence quenching by dissolved oxygen on aromatic compounds, determined by liquid chromatography coupled to fluorescence detection, has been investigated. Based on the fluorescence extinction coefficients and on the Stern-Volmer constants of aromatic compounds, the specific behaviour of each individual compound is explained.L'inhibition de la fluorescence des hydrocarbures aromatiques polycycliques...
pH effect on complex formation between β-LG and cinchonine is studied by fluorescence spectroscopy in aqueous buffer solutions in the 5.85 - 8.2 pH range, where cinchonine is essentially a monocation. Specific interactions were observed with very close affinity constant values (between 17.10 3 and 23 10 3 M -1 ), throughout the investigated pH, except pH 8.2 where...
The effect of membrane cholesterol incorporation on the process of oxygen diffusion was studied by fluorescence quenching of pyrenebutyric (PBA) or pyrenedodecanoic (PDA) acid. The membrane fluidity , studied by fluorescence polarization method with 4 probes with known specificity for membrane areas (6, 12-AS, DPH, TMA-DPH), decreased under increasing cholesterol/protein (C/Pt) ratio. Cholesterol...
