Mesoporous materials and methods of making the same
First Claim
1. A method for making a mesoporous material comprising:
- (a) forming an aqueous solution having an organometallic compound;
(b) adding a solution to the aqueous solution, the added solution comprising a pore forming material selected from the group consisting of monomeric polyols, polyacids, polyamines, carbohydrates, oligopeptides of at least two amino acid units, oligonucleic acids, carbonyl functional organic compounds, and mixtures and derivatives thereof to form a sol gel matrix by polycondensation;
(c) drying the sol gel matrix; and
(d) removing the pore forming material from the dried sol-gel matrix to thereby form a mesoporous material.

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.
