A new transparent, bio-inspired coating makes ordinary glass tough, self-cleaning, and incredibly slippery. Researchers created the glass honeycomb-like structure with craters, coating it with a Teflon-like chemical that binds to the honeycomb cells to form a stable liquid film. The film repels droplets of both water and oily liquids.

The new coating could be used to create durable, scratch-resistant lenses for eyeglasses, self-cleaning windows, improved solar panels, and new medical diagnostic devices.

Slides treated this way withstood damage and remained slippery after various treatments that can scratch and compromise ordinary glass surfaces and other popular liquid-repellent materials, including touching, peeling off a piece of tape, and wiping with a tissue.
