PEGylated (modified with polyethylene glycol) liposomes – their structures and properties

Liposomes are nanocarriers consisting of a phospholipid bilayer, similar in composition and structure to cell membrane. Such feature provides several possibilities related the transport delivery biologically active substances specific cells organisms. It is now becoming more popular modify lipid carrier shells achieve higher specificity efficiency into cells, reduce immunogenicity. The article aimed present properties, characteristics application liposomes modified with polyethylene glycol (PEG). most common modification coating PEG, then sterically stabilized PEGylated vesicles formed. PEGylation currently pillar liposomal technologies due high this type nanocarrier possibility attaching ligands polymer chains. This presents as carriers substances, their structures, types interactions special emphasis on liposomes.
