Abstract

Nanoporous hydrogels have been prepared by freezing-thawing method. Three types of porphyrins have been encapsulated into PVA hydrogels. It was demonstrated that the PVA hydrogels represent an efficient encapsulation vehicle for porphyrins. Hydrogels prepared from high molecular mass PVA have a better sorption profile for porphyrins, and are better suited for the preparation of controlled release vehicles..
