The synthesis, characterization and delivery of poly(ethylene glycol) (PEG)-modified liposomes as drug carriers were investigated. A NeutrAvidin-rich surface was also created onto which PEG-biotinylated liposomes were docked, exploiting the well known high affinity of avidin-like proteins for biotin. It was found that the amount of bound NeutrAvidin was higher on surfaces coupled with biotinylated PEG under cloud point conditions, compared to binding onto surfaces prepared in water. Characterization of biomaterial surfaces modified via diaminopropane (DAP) interlayers, covalently coupled PEG-Biotin and bound NeutrAvidin also demonstrated their suitability as docking platforms for PEGylated liposomes.
