The field of nanotherapeutics is the application of nanotechnology to medicine and drug development.
Polyethylene glycolPolyethylene glycol (PEG) is often covalently attached to LNP phospholipids on the outer side which improves stability. Also, PEGylated phospholipids improve the stealth of the drug product as it helps shield from the immune system. The modification prevents blood plasma proteins from absorbing into the liposome surface, allowing more circulation time. Hybrid nanoparticles incorporate PLA or PGLA polymers within a lipid monolayer to facilitate controlled drug release.
