Influence of electrical polarization on thrombogenicity of titania nanotubes

International Journal of Ceramic Engineering &Science, Volume 6, Issue 3, May 2024.
Abstract The development of hemocompatible biomaterials with antithrombogenic surface coatings remains a challenge in cardiovascular applications. There is interest in negatively charged surfaces that inhibit thrombus formation through electrostatic repulsion between the biomaterial surface and negatively charged platelets.
