Abstract: Provided is a method of controlling local release of target compounds by patterning a hydrogel carrying a bone morphogenetic protein or anticancer drug as the target compounds onto an electrospun nanoporous membrane. The hydrogel is capable of controlling local release of the bone morphogenetic protein or anticancer drug as a carrier of the bone morphogenetic protein or anticancer. And the electrospun nanoporous membrane performs a basic function of the membrane of preventing infiltration of connective tissue. Thus, there is an advantage in that the hydrogel patterned nanoporous membrane can facilitate generation of controlled bone in a local region and degradation of cancer in a local region.
