The Impact of Propanol, N-Butanol and Pentanol on Aqueous Dispersions of Sonicated Liposomes. EPR Study

Abstract This paper presents the effect of selected alcohols on the fluidity of liposome membranes obtained in sonication of DPPC lecithin. Using the EPR technique, the duality of propanol, n-butanol and pentanol on the behaviour of the aqueous dispersion of liposomes was demonstrated. It was shown that after exceeding a certain concentration, these alcohols initiate dispersion foaming, leading to phase separation: liposome dispersion - lipid foam. The influence of the shape of the molecule and the length of hydrocarbon chains on the effectiveness of destabilisation of the structure of lipid membranes was indicated.
