• 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...
• 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...

  Fouling Marine Fouling
  Marine 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...

  Efficient Recovery of Stem Cell Sheets
  See 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. Credit: Wyss Institute at Harvard University

  Fluid Gate
  In this video, the fluid-based gating mechanism separates gas and water. The fluid-filled pores system leverages pressurization to control the opening and closing of its liquid gates, making it extremely precise at separating mixed materials. Credit: Wyss Institute at Harvard University

  Bioinspired Blood Repellent Coating
  In this video, Wyss Institute Founding Director Don Ingber, Core Faculty member Joanna Aizenberg, Staff Scientist Dan Leslie and Postdoctoral Fellow Anna Waterhouse explain how a coating they developed using FDA-approved materials could prevent blood clotting in medical devices without the use of blood thinners.

  New coating turns glass into superglass
  A 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. To learn more, go to Credit: Wyss Institute at Harvard University

  SLIPS
  ‘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...
