Biological membranes are known to play a key role in controlling life-related molecular functions (eg, active/passive transport, diffusion, filtration, selective permeation, etc.). Lipid bilayer membrane vesicles (ie, liposomes) are small assemblies of amphiphilic molecules bearing both hydrophilic and hydrophobic groups and they offer promising prospects for the understanding of biological membranes. If less-catalytically active small molecules can ...
