Aspects of the disclosure feature a method that comprises preparing an agent-cyclodextrin complex. Preparing the agent-cyclodextrin complex includes contacting a first composition comprising an agent with a porous cyclodextrin-metal organic framework to form a second composition comprising an agent-cyclodextrin-metal organic framework complex, the cyclodextrin-metal organic framework including a plurality of cyclodextrin molecules and at least one metal cation. Preparing the agent-cyclodextrin complex also includes dissolving the agent-cyclodextrin-metal organic framework complex in an aqueous solvent to form a third composition including the agent-cyclodextrin complex.
