A method for coating a substrate with silane that comprises contacting in an inert environment a substrate with a vapor containing a bifunctional silane, preferably a bifunctional silane containing an acrylic functionality. The method may further comprise the step of attaching a coating of polyacrylamide to the acrylic functionality by in-situ polymerization or the step of immobilizing acrylic-modified molecules by copolymerization with the acrylic functionality of the bifunctional silane. The substrate may be a capillary, a microchip, a bead, or a slide, preferably of glass. A substrate coated using the instant method, as well as a method for reducing EOF in capillaries used for electrophoresis are also disclosed. |
