The instability behaviour of several supported liquid membranes (SLMs) has been studied for a system in which nitrate ions are removed from an aqueous feed phase and concentrated in a stripping phase. The composition of the aqueous phases and of the membrane liquid has been determined after the aqueous phases had flowed parallel to the membranes for a period of six days. From the experimental d...

In this study we investigate silica nanoparticle (SiO2NP) effects on the structure and phase properties of supported lipid monolayers and bilayers, coupling surface pressure measurements, fluorescence microscopy and atomic force microscopy. SiO2-NPs typically in size range of 10nm to 100 nm in diameter are tested. Our results suggest first that lipid molecules organization depends to their natu...

Cells are complex systems whose interaction with nanocarriers, i.e., liposomes, continuously under investigation to improve drug uptake. Model membranes can facilitate the understanding of processes involved in fusion or endocytosis. In this work, we engineered two different lipid model membranes, vesicles and supported bilayers (SLBs), mimicking composition HeLa cell plasma membrane. We charac...

Abstract The dynamic reorganization of plasma membrane nanodomains (lipid rafts) plays a key role in host cell infection by human pathogens. Bacteria can induce the lipid rafts as result interactions between bacterial lectins and raft glycosphingolipids (GSLs). However, it is still unclear how such trigger initial stage mechanism. Here, we study GSL globotriaosylceramide (Gb3), receptor involve...
