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

摘要

A multi-layer crosslinked gelatin gel structure having a layer structure that plural layers of crosslinked gelatin gel crosslinked by irradiating gelatin or a gelatin derivative with electron beam under an oxygen-containing atmosphere are arranged adjoiningly to each other, a preparation for release of a bioactive factor with the bioactive factor contained in the multi-layer crosslinked gelatin gel structure, and production processes thereof.
