Abstract: A synthetic polymeric form of carbon (Tetracarbon™) which exhibits some properties similar to biological tissues. Tetracarbon is highly biocompatible and may have application in medicines and microelectronics. Tetracarbon is a biocompatible substrate coating made by depositing short linear chains of carbon stores upon the surface of the substrate. The carbon chains are non-turbostratic and oriented perpendicular to the substrate surface and are densely packed parallel to one another in hexagonal structures with the distance between the carbon chains being between 4.8-5.03 ANG.. A layer of Tetracarbon is identical to an adjacent layer and randomly shifted laterally relative to each other.
