Hybrid porous materials useful for releasing bioactive materials in response to an external stimulus at a constant release rate are formed of a porous inorganic gel having a polymer network integrated within the pores of a porous gel. The hybrid porous material is made by forming a mixture of a polymer precursor, a cross linking agent, an initiator, an alcohol, a ceramic precursor, water and an acid. The mixture is then formed either by first polymerizing the polymer precursor to form a polymer network, and then forming the ceramic precursor into a porous inorganic gel, or by first forming the ceramic precursor into a porous inorganic gel and then polymerizing the polymer precursor to form a polymer network. Either approach will yield a porous inorganic gel having a polymer network integrated within the pores of the porous gel.
