A drug delivery composition is disclosed which includes a triple salt proxy functional group and at least one amino acid functional group. A method of forming the drug delivery composition includes reacting a triple salt with at least one amino acid in an aqueous environment. A biodegradable fabric is disclosed which includes a polymerized structure of a triple salt proxy functional group and at least one amino acid functional group.

Disclosed are nanocomposite oxygen-generating cryogels and their uses in reducing hypoxia in a biological tissue, such as a tumor. Methods of treating cancer with the disclosed cryogels are also provided.

The present invention relates to an injectable hydrogel rod using a crosslinked hydrogel, a method for manufacturing same, and biomedical use thereof. According to the present invention, by adjusting the contents of a polymer, an enzyme and hydrogen peroxide to a certain ratio to manufacture an injectable hydrogel rod, the initial release amount of a drug injected into the hydrogel rod is controlled, and thus, compared to existing hydrogel-based injectable implants, the hydrogel rod exhibits sustained release above an effective concentration for a long period of time and greatly reduces elimination into surrounding tissues, which may result in an increased therapeutic effect and remarkably reduced side effects.

Hydration mediums, assemblies containing hydration mediums and methods of making the same.
