CROSSLINKED GELATIN GEL MULTILAYERED STRUCTURE, CARRIER FOR BIOACTIVE FACTOR, PREPARATION FOR RELEASE OF BIOACTIVE FACTOR, AND THEIR PRODUCTION METHODS

摘要

Disclosed is a crosslinked gelatin gel multilayered structure having a layered structure comprising multiple crosslinked gelatin gel layers arranged adjacent to one another, wherein each of the crosslinked gelatin gel layers is produced by crosslinking gelatin or a gelatin derivative by irradiation with electron beam in an oxygen-containing atmosphere. Also disclosed is a preparation for releasing a bioactive factor, which comprises the crosslinked gelatin gel multilayered structure and the bioactive factor contained in the crosslinked gelatin gel multilayered structure. Further disclosed are a method for producing the multilayered structure and a method for producing the preparation.
