Abstract
Mesoporous materials and a method for making such materials is disclosed in which the mesoporous materials are made by forming an aqueous solution having an organometallic compound; adding a solution comprising a pore forming material selected from the group consisting of monomeric polyols, polyacids, polyamines, carbohydrates, oligopeptides, oligonucleic acids, carbonyl functional organic compounds, and mixtures and derivatives of these materials to form a sol get matrix by polycondensation; drying the sot gel matrix; and removing the pore forming material from the dried sot-gel matrix to thereby form a mesoporous material. The mesoporous materials have pore diameters of from about 20 å to about 100 å and may be used with a biologically active agent immobilized within the pores of the mesoporous material and introduced into a biological system.
