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: Synthetic brochosomes can be prepared by disposing a monolayer of first polymer microspheres on a substrate and forming a layer of metal on the monolayer of the first polymer microspheres. A monolayer of second polymer microspheres is then disposed on the layer of metal to form a template. The second polymer microspheres are smaller than the first polymer microspheres. A brochosome material is then electrodeposited on the template. The brochosome material is selected from the group consisting of a metal, a metal oxide, a polymer or a hybrid thereof. The first polymer microspheres and the second polymer microspheres are then removed to form a coating of synthetic brochosomes of the brochosome material on the substrate.

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 substrate with a switchable surface has been developed that can rapidly switch its surface character such as between two distinct liquid-repellent modes: (1) a superhydrophobic mode and (2) a slippery mode. Such surfaces have demonstrated adaptive liquid repellency and water harvesting capabilities.

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.

Abstract: A robust and self-healing coating has been developed by incorporating a thermally self-healing chemical coating on smooth and/or roughened solid. When the chemically coated solid is combined with a lubricating fluid, the material system is capable to repel a broad range of liquids and solids. The thermally self-healing chemical coating may be applied on various industrial metals, glass and plastics, and has shown exceptionally physical and chemical robustness as compared to state-of-the-art liquid-repellent coatings.
