    Abstract: A method is disclosed for providing a patterned surface wherein predetermined regions of the surface are masked with a self-assembled monolayer (nullSMAnull) covalently bound to a brush polymer overlayer. The remainder of the substrate surface will generally be functionalized with a second self-assembled monolayer. Preferably, the method involves a microcontact printing technique, wherein a molecular moiety capable of spontaneously forming an SMA upon transfer to a surface is nullstampednull onto a substrate surface, followed by growth (or covalent attachment) of a polymer on exposed functional groups within the SMA molecules. Coverage of surface regions with both an SMA and a polymer overlayer provides a number of advantages, particularly with regard to surface masking during etching and the like. The method is useful in the manufacture of microelectronic circuitry, biosensors, high-density assay plates, and the like.

    Abstract: PROBLEM TO BE SOLVED: To provide a liquid droplets guide structure capable of controlling a moving direction of the droplets on the surface of a material body, particularly a liquid droplets guide structure appropriate for application to a water repellent glass and a coating for automotive use. SOLUTION: The liquid droplets guide structure comprises, on a surface, a strip-shaped surface part A and a strip-shaped surface part B having a water-reduced contact angle smaller than that of the strip-shaped surface part A, such strip-shaped surface part A and strip-shaped surface part B being disposed side by side. The strip-shaped surface part A and strip-shaped surface part B satisfy the following equation (1): θ A -θ B =10° to 140° (where θ A and θ B represent water-reduced contact angles at 20°C of the strip-shaped surface part A and B respectively).
