Blood‐Repellent Surfaces: Superhydrophobic Blood‐Repellent Surfaces (Adv. Mater. 24/2018)

Abstract

Blood-repellent superhydrophobic surfaces aim toward reducing the thrombogenicity of the surfaces of blood-contacting devices and implants. In article number 1705104, Ville Jokinen, Esko Kankuri, Robin H. A. Ras, and co-workers highlight several recent examples of such surfaces, where, for example, blood droplets in the superhydrophobic Cassie state roll off a micro and nanostructured PDMS–titania hybrid surface easily, without leaving a stain. Several mechanisms that lead to blood repellency are proposed, focusing mainly on platelet antiadhesion.
