    摘要: A structurally rigid biodegradable foam scaffold useful for cell transplantation is provided. The foam can be loaded with nutrients and/or drugs that elute from the foam during transplant to promote growth of the cells. The foam, which features a continuous network of pores, is fabricated using a novel method involving phase separation and consequent expansion upon sublimation of a liquid solvent, preferably naphthalene.
