摘要:
The invention provides poly(alkyleneimine)-graft-biodegradable polymers and methods for preparing such polymers. The poly(alkyleneimine)-graft-chitosan polymers may optionally contain a targeting element. The poly(alkyleneimine)-graft polymers may be used to deliver a bioactive agent into a cell.
