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 1):
An article for repelling a biological material comprising a slippery surface, the slippery surface comprising:\n a lubricating fluid layer, wherein the lubricating fluid is immiscible with a biological material, the lubricating layer forming an ultra-smooth surface over a roughened solid substrate; wherein the lubricating fluid adheres to the substrate and the substrate is preferentially wetted by the lubricating fluid, the solid substrate and lubricating fluid forming a slippery surface configured and arranged to contact a biological material; wherein the article is selected from the group consisting of dialysis machines, central veno-venous hemofiltration devices, extracorporeal membrane oxygenation equipment, or the article is a device selected from the group consisting of an organ, artificial organ, implant, and combinations thereof.
