Latest Patents
One of Dolnik's latest patents involves the suppression of electroosmosis with hydrolytically stable coatings. This invention addresses the challenges faced with silica-containing materials, particularly the inner walls of silica capillaries used in electrophoretic separations. The process involves coating these surfaces with an organic polymer layer to reduce or eliminate surface charges. The method includes converting silanol groups on the surface to silicon halide groups, which are then reacted with an organometallic reagent to form stable Si--R groups. This results in a monomolecular noncrosslinked polymer layer that is directly linked to the silica through a stable Si--C bond, maintaining integrity across a wide range of pH conditions.
Another significant patent pertains to the formation of capillary gels through spatially progressive polymerization. In this process, a charged polymerization initiator is electrophoretically drawn into a capillary tube filled with monomer, crosslinking agent, and catalyst. The controlled movement of the initiator allows for a sharp leading edge, facilitating progressive polymerization and compensating for the shrinkage inherent in the reaction. This innovative approach avoids discontinuities in the gel, enhancing the overall quality of the polymer structure.
