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:
Improved method of forming a patterned self-assembled monolayer on a surface and derivative articles are provided. According to one method, an elastomeric stamp is deformed during and/or prior to using the stamp to print a self-assembled molecular monolayer on a surface. According to another method, during monolayer printing the surface is contacted with a liquid that is immiscible with the molecular monolayer-forming species to effect controlled reactive spreading of the monolayer on the surface. Methods of printing self-assembled molecular monolayers on nonplanar surfaces and derivative articles are provided, as are methods of etching surfaces patterned with self-assembled monolayers, including methods of etching silicon. Optical elements including flexible diffraction gratings, mirrors, and lenses are provided, as are methods for forming optical devices and other articles using lithographic molding. A method for controlling the shape of a liquid on the surface of an article is provided, involving applying the liquid to a self-assembled monolayer on the surface, and controlling the electrical potential of the surface.
Abstract:
A method is proposed with which chemically defined bodies can be deposited on a substrate. Therefor, the bodies are fixed with a predetermined orientation on a stamping means which is then approached to the substrate whereby the bodies are deposited. While releasing the stamping means the bodies remain on the substrate keeping their orientation.

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).
