Abstract
A base body contains a substrate that is at least partially coated with a carbon-containing layer. The carbon-containing layer is at least partially functionalized with a molecule that is bound directly or via at least one linker or functional group to the carbon-containing layer. The base body, which has a functionalized carbon-containing surface, is capable of influencing biological processes during a corresponding functionalization.
Claims27
An implant, comprising:
- a substrate;
- and
- a carbon-containing layer at least partially coating said substrate, said carbon-containing layer formed of at least 80% diamond crystals and said carbon-containing layers being at least partially functionalized with a growth factor, protein, or peptide bound to said carbon-containing layer either directly or via at least one linker or functional group.
