SLIPS (Slippery Liquid Infused Porous Surface) was inspired by carnivorous pitcher plants, whose slippery, cylindrical leaves slide insects into the digestive juices at the base of the plant. The surface of the leaves' spongelike texture is infused with water, which repels the sticky oils on insects' feet. Lead researcher Joanna Aizenberg, a material scientist at Harvard, and her colleagues created an artificial version of the leaves surface, immobilizing a "lubricating film" (3M's Fluorinert FC-70 perfluorinated fluid) inside a similarly spongy layer of Teflon. The result is "omniphobic," repelling both water and oil-based materials. Liquids from oil and water to blood all roll right off the material when it's tilted at merely 2 degrees, compared to 5 to 30 degrees for other surfaces.
