Abstract:
A self-healing, scratch resistant slippery surface that is manufactured by wicking a chemically-inert, high-density liquid coating over a roughened solid surface featuring micro and nanoscale topographies is described. Such a slippery surface shows anti-wetting properties, as well as exhibits significant reduction of adhesion of a broad range of biological materials, including particles in suspension or solution. Specifically, the slippery surfaces can be applied to medical devices and equipment to effectively repel biological materials such as blood, and prevent, reduce, or delay coagulation and surface-mediated clot formation. Moreover, the slippery surfaces can be used to prevent fouling by microorganisms such as bacteria.

Claim (Index 2):
The article of  claim 1 , wherein the slippery surface of the article satisfies the following condition\n \u03b3 BX  cos \u03b8 BX \u2212\u03b3 AX  cos \u03b8 AX >0 wherein \u03b3 AX  is the interfacial energies of the biological material with a surrounding medium; wherein \u03b3 BX  is the interfacial energies of the lubricating fluid with the surrounding medium; wherein \u03b8 AX  is the equilibrium contact angle of the biological material on a flat solid surface immersed under the surrounding medium; and wherein \u03b8 BX  is the equilibrium contact angle of the liquid of the lubricating fluid on a flat solid surface immersed under the surrounding medium.
