Disclosed herein are compositions including polymers functionalized with oxanorbornadiene ("OND") crosslinkers and various within, where the materials and formulations thereof enable controlled, extended release of cargos such as therapeutic, antigenic, diagnostic, and/or analytical agents. Also disclosed is the use of physical entrapment of the cargo, covalent connection of the cargo to polymer via cleavable linkages, and combinations thereof. These combinations provide different patterns and durations of release of cargo molecules. Also disclosed herein are the methods of making and using the same.
