Membranes can be fabricated either from lipid or polymer molecules, leading to the
formation of liposomes or polymersomes. In all types of liposomal membranes, the issue of …

Liposomes are lipid vesicles made of one or multiple lipid bilayers surrounding an internal
aqueous core. They are broadly employed as models to study membrane structure and …

Nanoparticles offer clear advantages for both passive and active penetration into
biologically important membranes. However, the uptake and localization mechanism of …

Polyethylenimine (PEI) has been demonstrated as an efficient DNA delivery vehicle both in
vitro and in vivo. There is a consensus that PEI-DNA complexes enter the cells by …

Polycations are an attractive class of macromolecules with promising applications as
