Abstract
Provided herein are methods for preparing nano-macroporous glass articles, such as bioscaffolds, from starting materials such as phosphosilicate glasses made by melt-quench methods, mixed with a soluble pore former such as a sugar, followed by steps of dissolving, heating, and leaching to yield a glass composition having a highly interconnected system of both macropores and large scale nanoporosity.
