Abstract
A method for manufacturing a porous ceramic scaffold having an organic/inorganic hybrid coating layer containing a bioactive factor includes (a) forming a porous ceramic scaffold; (b) mixing a silica xerogel and a physiologically active organic substance in a volumetric ratio ranging from 30:70 to 90:10 and treating by a sol gel method to prepare an organic/inorganic hybrid composite solution; (c) adding a bioactive factor to the organic/inorganic hybrid composite solution and agitating until gelation occurs; and (d) coating the porous ceramic scaffold with the organic/inorganic composite containing the bioactive factor added thereto. In accordance with the method, the porous ceramic scaffold may be uniformly coated with the organic/inorganic hybrid composite while maintaining an open pore structure, and stably discharge the bioactive factor over a long period of time.
