The University of Chicago received US Patent No. 6,656,725, “Method of fabrication of microarray of gel-immobilized compounds on a chip by copolymerization.” The patent covers a system for making polymerized molecules by contacting a solution-containing monomer to a solid substrate to form discrete accumulations, which are contacted with a polymerizing agent to prevent cross contamination. The process includes the creation of porous entities, each capable of containing a different molecule, and each capable of being positioned differentially.
