    Abstract: A sample plate for mass spectrometric analysis of a specimen is provided comprising a substrate having an electrically conductive surface, a mask applied to the electrically conductive surface. The mask is applied to the substrate with a rough surface to form at least one sample site. The sample site comprises a central portion formed from the electrically conductive surface and a marginal portion formed from the mask where the marginal portion is more hydrophobic than the central portion.

    Abstract: Improved methods 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: The assay plate includes a substrate having an substrate surface and at least one raised pad extending from the substrate surface. The raised pad includes a substantially planar sample receiving surface configured for holding a sample thereon for in-situ experimentation. The sample receiving surface preferably has at least one sharp edge at the junction between a sidewall coupling the sample receiving surface to the substrate surface. The sample receiving surface is preferably a circle, oval, square, rectangle, triangle, pentagon, hexagon, or octagon shape that is sized to hold a predetermined volume of the sample. A method of using the above described assay plate is also provided. Once a raised pad extending from a substrate is formed, a sample is deposited on the raised pad. Experiments are subsequently performed using the sample on the raised pad.
