    Abstract: A biochemical analysis system capable of sample preparation and processing can include at least one inlet channel having a non-fouling, slippery surface to autonomously transport a fluid sample to a chamber by a geometry of the at least one inlet channel. The at least one inlet channel can include a first end, which is open and exposed, and a second end connected to the chamber for mixing and reaction of the fluid sample, and the at least one inlet channel can include a converging or diverging angle.

    Abstract: A process for preparing a repellant smooth surface includes applying a coating composition onto a smooth surface of a substrate having hydroxyl functional groups thereon and an average roughness Ra of less than 4 μm. The coating composition includes: (i) a polymerizable silane or siloxane or both selected from the group consisting of dimethyldimethoxysilane, dimethoxy-methyl(3,3,3-trifluoropropyl)silane, dimethoxy(methyl)octylsilane, diethoxydimethylsilane, (ii) a solvent and (iii) an acid catalyst. The process further includes polymerizing the silane or siloxane or both from the hydroxyl functional groups on the smooth surface of the substrate to form a chemical layer of graft polymers having ends anchored to the smooth surface and applying a lubricant coating over the formed chemical layer to adhere and maintain the lubricant on the smooth surface and form a lubricant-entrenched smooth surface as the repellant smooth surface.

    Abstract: Substrates having a textured surface that can maintain or improve droplet mobility in both the Cassie and Wenzel states include a textured surface and a conformal lubricant layer thereover. The textured surface can include a plurality of raised first elements and a plurality of second elements thereon and the conformal lubricant layer over the plurality of raised first elements and covering the plurality of second elements. The plurality of raised first elements can have an average height of between 0.5 μm and 500 μm, and the plurality of second elements can have an average height of between 0.01 μm and 10 μm. Such substrates can be prepared by texturing a surface of a substrate with a plurality of raised first elements and a plurality of second elements thereon; optionally silanizing the textured surface and applying a lubricant layer over the plurality of raised first elements and between the plurality of second elements.

    Abstract: A coated smooth surface of a substrate repels liquids and viscoelastic materials and can have anti-staining and anti-biofouling properties. The smooth surface can be coated by applying a chemical layer on the surface and a lubricant. Such coated surfaces are useful for use in toilets, urinals, or other devices for the processing of liquids and viscoelastic materials such as solid or semi-solid metabolic waste of human digestive system. Such coated surfaces can also be applied to windows for buildings or vehicles such as automobiles or camera lenses to repel liquids (e.g., rain), ice, frost, insect residues, and birds' feces.
