Novel composite graphene oxide (GO)/poly(allylamine hydrochloride) (PAH) multilayer capsules have been fabricated by layer-by-layer (LbL) assembly. They were found to possess unique permeability properties compared to traditional LbL capsules. These hybrid capsules showed special "core-shell'' loading property for encapsulation of dual drugs simultaneously into the core and shell of the capsules respectively.
