PURPOSE: A nanoporous membrane with nanopores, which is a depot system capable of controlling the release of functional proteins in cosmetics is provided to be used as a nanoporous carrier based on a block copolymer. CONSTITUTION: A nanoporous membrane is prepared using PS-b-PMMA[polystyrene-block-poly (methyl methacrylate) polymers. The particle size of nanopores of the nanoporous membrane is 10-20 nm. The average of the particle size is 15 nm. A method for delivering antibody-based proteins constantly maintains release rate using the nanoporous membrane. The nanoporous membrane is used in a sustained release drug delivery system of the antibody-based proteins. |
