Tethered Liquid Perfluorocarbon (TLP), a non-stick coating for medical devices
Every device implanted in the body or in contact with flowing blood faces two critical challenges that can threaten the life of the patient it is meant to help: blood clotting and bacterial infection. To confront this challenge, Wyss Institute researchers created a super-repellent, Thin Layer Perfluorocarbon (TLP) coating specifically designed to prevent clot formation...
Phase-Separating Liquid Gated Membranes
Just like pores in living organisms that control the absorption and excretion of fluids, gases and solids in response to their environments, flow-gating membranes have proved very useful for many mechanical systems, such as gas and liquid separators, dialysis machines, or open heart bypass pumps. But conventional approaches to create synthetic “gated pores” within those...
SLIPS (Slippery Liquid-Infused Porous Surfaces)
The need for an inexpensive, super-repellent surface cuts across a vast swath of societal sectors—from refrigeration and architecture, to medical devices and consumer products. Most state-of-the-art liquid repellent surfaces designed in the last decade are modeled after lotus leaves, which are extremely hydrophobic due to their rough, waxy surface and the physics of their natural...
Video/AnimationFouling Marine FoulingMarine fouling occurs when organisms attach themselves to underwater objects like boats, rope, pipes and building structures. Mussels are one of the biggest culprits. Once attached, they are difficult to remove, leading to operational downtime, increased energy use and damage. Paints and coatings are currently used to prevent marine fouling, but are frequently toxin-based and not...
Video/AnimationEfficient Recovery of Stem Cell SheetsSee in this video how an intact sheet of mesenchymal stem cells, stained with a violet dye, can be lifted off the infused polymer substrate in the culture dish using a filter paper and transferred to a new surface.

Video/AnimationNew coating turns glass into superglassA transparent new coating makes ordinary glass tough, ultraslippery, and self-cleaning. The coating is based on SLIPS — the world’s slipperiest synthetic substance. Here, a droplet of dyed octane quickly beads up and rolls off a watch glass with the new coating.

Video/AnimationSLIPS‘SLIPS’ technology, inspired by the slippery pitcher plant that repels almost every type of liquid and solid, is a unique approach to coating industrial and medical surfaces that is based on nano/microstructured porous material infused with a lubricating fluid. By locking in water and other fluids, SLIPS technology creates slick, exceptionally repellent and robust self-cleaning...
Video/AnimationSLIPS: Keeping Ice AwayWhat if we could design surfaces that prevent ice formation? ‘SLIPS’ technology, inspired by the slippery pitcher plant that repels almost every type of liquid and solid, is a unique approach to coating industrial and medical surfaces that is based on nano/microstructured porous material infused with a lubricating fluid. By locking in water and other...
