摘要：
A method of preparing a hydrogel for delivery of an active agent. The method includes providing an aqueous solution that includes the active agent； dispersing or dissolving a gel-forming polymer in the aqueous solution to form a polymer solution； and cross-linking the polymer in the polymer solution to form the hydrogel which encapsulates the active agent.
