Ultrananocrystalline diamond (UNCD™) coating for new-generation implantable medical devices/prostheses

Abstract

Ultrananocrystalline diamond (UNCD™) coating for new-generation implantable medical devices/prostheses In this materials science piece, Orlando Auciello, describes the development of a unique multifunctional/best biocompatible ultrananocrystalline diamond (UNCDTM) coating for new-generation implantable medical devices and prostheses. Materials’ surfaces of vital medical devices, such as silicon (Si) microchip (artificial retina) implanted on human retina, restoring partial vision to people blinded by genetically induced photoreceptors degeneration, and metallic dental implants, are attacked chemically by eyes’ fluids or oral fluids respectively. Metallic stents/artificial heart valves, inside human blood vessels, activate blood enzymes, inducing coagulation, and fibrinolytic, leading to thrombus formation (i.e., blood clot in blood vessels, obstructing blood flow or loosed clot getting stuck in arteries/veins’ walls, causing life-threatening stroke/heart attack.
