Abstract
Described herein are hydrophobic coating compositions having unique physical properties. The coating compositions are composed of silicon oxide nanoparticles and silicon nanoparticles modified with a perfluorolkylsiloxane. The coating compositions can be applied to any article or any surface of an article where it is desirable to reduce or prevent the growth of bacteria. The articles coated with the hydrophobic coating compositions are subsequently treated with a nitric oxide releasing compound that can prevent the growth of bacteria and adhesion of platelets on the article.
