Many modern cosmetic or sunscreen products contain nano-sized components. Nanoemulsions are transparent and have unique tactile and texture properties; nanocapsule, nanosome, noisome, or liposome formulations contain small vesicles (range: 50 to 5000 nm) consisting of traditional cosmetic materials that protect light-or oxygen-sensitive cosmetic ingredients. Transdermal delivery and cosmetic re...

We present for the first time an acoustofluidic method to enrich cell-derived extracellular vesicles (EV) from human plasma, enabling rapid access to a biological nano-compartments rich in biomarkers. The system was characterized using polystyrene nanoparticles. Human EVs from cell-free plasma were successfully enriched and analyzed using a FACS. The technique enables EV-recovery from small sam...

The lipid bilayer of model membranes, liposomes reconstituted from cell lipids, and plasma membrane vesicles and spheres can separate into two distinct liquid phases to yield lipid domains with liquid-ordered and liquid-disordered properties. These observations are the basis of the lipid raft hypothesis that postulates the existence of cholesterol-enriched ordered-phase lipid domains in cell me...

Multilamellar vesicles (noisome) of polyoxyethylene alkyl ether surfactants (Brij 52, 72, 76 and 92) were prepared using classic film hydration method. Vesicle formation ability of the surfactants was assessed in presence or absence of cholesterol. All used surfactants formed vesicles in the absence of cholesterol. Recombinant human insulin was used as a model protein drug to investigate encaps...

Theoretical analysis and Computer simulations have proven to be cost-effective and powerful tools in scientific studies of materials, particularly at nano-scale where synthesis of nano-structures, interpretation of their observed character and exploration of new structures are not always straight forward. We present here fundamental principles of techniques used today for computational simulati...
