Solvent casting property for the scaffolds preparation is very simple, easy and inexpensive. It does not require any large equipment; it is totally based upon the evaporation of some solvent in order to form scaffolds by one of the two routes. One method is to dip the mold into polymeric solution and allow sufficient time to draw off the solution; as a result a layer of polymeric membrane is created. Other method is to add the polymeric solution into a mold and provide the sufficient time to evaporate the solvent that create a layer of polymeric membrane, which adhere to.
