Abstract
The present invention is directed to a method of making a foam, the method including contacting a polymer solution with a surface of a mold, the solution containing dissolved therein a biocompatible polymer, the mold containing disposed on at least one surface thereof a three-dimensional negative configuration of a predetermined micropattern to be disposed on and integral with at least one surface of the foam, lyophilizing the solution while in contact with the surface of the mold and removing the lyophilized micropatterned foam from the mold.
