“…This simple rule is not valid, however, for all type of surfactants and properties. For example, the cloud points of fluorinated poly(oxyethylene) surfactants are lower than those of hydrocarbon analogues even twice longer (Mathis et al, 1984). Short alkyl spacers do not obey the rule either, leaving control of adsorption and micellisation to the F-chain (Sadtler et al, 1998a).…”

“…In a first part, we have investigated the phase behavior of C 7 F 15 C 2 H 4 (EO) 7 in water. Since fluorinated surfactants allow cosolubilization of water and perfluoroalkanes [37][38][39], we have a look at the effect of perfluorodecalin (PFD) on the surfactant phase behavior. Based on the obtained results we shed some light on the role played by PFD on the swelling mechanism and pore arrangement of the recovered mesostructured silica.…”

Ultraviolet–circular dichroism spectroscopy and potentiometric study of the interaction between human serum albumin and sodium perfluorooctanoate

The interaction of a fluorinated surfactant, sodium perfluorooctanoate, with human serum albumin (HSA) has been investigated by a combination of ultraviolet-circular dichroism (UV-CD) spectroscopy and potentiometry (by a home-built ion-selective electrode) techniques to detect and characterize the conformational transitions of HSA. By using difference spectroscopy, the transition was followed as a function of temperature, and the data were analyzed to obtain the parameters characterizing the thermodynamics of unfolding. The results indicate that the presence of surfactant drastically changes the melting unfolding, acting as a structure stabilizer and delaying the unfolding process. Potentiometric measurements were used to determine the binding isotherms and binding capacity for this system. The isotherm shows a high affinity of surfactant molecules for HSA. The average number of surfactant molecules absorbed per protein molecule (at 28 mM of surfactant concentration) was found to be approximately 900, about 6 g of surfactant per gram of protein. The shape of the binding capacity curve and the relation between binding capacity and extend of cooperativity were examined. From these analysis, the values of g (number of ligand-binding sites), KH (Hill binding constant), and nH (Hill coefficient) were determined.
