Abstract

Disclosed herein is an implantable medical device including an antimicrobial layer. The antimicrobial layer may include a first distinct size of silver nanoparticles, a second distinct size of silver nanoparticles, and a third distinct size of silver nanoparticles. The antimicrobial layer extends over a surface of the implantable medical device, and, in some instances, the surface of the implantable medical device may serve as a substrate on which the antimicrobial layer is deposited.
