  • Production of Polymer Matrix for Delivery (PMD)
    Publication number: 20070128286
    Abstract: This invention is a means of production of polymer matrix for delivery. This invention employs amino acid chelated minerals as an ionic cross-linking agent, which forms colloidal solution containing delivery molecules after fully mingling with chitosan-acid solution that contains delivery molecules. This invention uses amino acid chelated minerals and chitosan to produce polymer matrix and then deliver molecules while proceeding ionic cross-linking. This is an innovative procedure.
