OBJECTIVE to prepare a novel brain targeting system, lactoferrin conjugated self-assembled polymer vesicles (Lf-PVs), which the brain delivery property had been evaluated in vivo.

Polymersome micelles and niosomes are the medication vehicle composed by amphiphilic block copolymer self-assembling in water.

The potential applications of the polymeric vesicles in some fields, such as micro-circumstance, the release of drug, gene engineering and biomineralization were introduced.
