Abstract

© 2022 IEEE.Thrombogenesis and infections due to pathogen transmission caused by medical equipment interfaces are one of the biggest health problems that threaten human life. One of the recent approaches to overcome these problems is superhydrophobic surfaces with low surface energies and micro/nano surface roughness. Here, medical equipment interfaces such as gloves, lancets, surgical drapes and gowns have been made superhydrophobic. These superhydrophobic surfaces exhibited high blood repellency with a static contact angle of 172° against blood, allowing continuous blood flow without leaving any residue on the surface. Furthermore, these coatings perfectly suppressed the biofilm formation by preventing the adhesion of the most common S. aureus and E. coli bacterial species to the surfaces. Superhydrophobic material, which has over 100% biocompatibility in vitro, also exhibited high hemocompatibility, giving hope for its applicability to a number of in-body medical device interfaces such as catheters, artificial vessels, and implants.
