Quarternized titanium-nitride anti-bacterial coating for dental implants
Disclosed herein is a method for forming an anti-microbial layer on an apparatus. Also disclosed is a method for improving the anti-bacterial properties of a titanium device coated with titanium-nitride (TiN). Also disclosed is a medical apparatus comprising an anti-microbial layer prepared by the disclosed methods. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.
1. A medical apparatus, comprising a titanium layer coated with a titanium nitride layer, wherein the titanium nitride layer consists of titanium nitride quaternized with a C1-C6 alkenyl bromide or C1-C6 alkyl bromide.
2. The apparatus of claim 1 , wherein the C1-C6 alkenyl bromide is allyl bromide.
3. The apparatus of claim 1 , wherein the titanium nitride layer has a thickness of about 50 Å to about 1000 Å.
4. The apparatus of claim 3 , wherein the titanium layer having has a thickness of about 100 Å to about 3000 Å.
5. The apparatus of claim 1 , wherein the titanium nitride layer consists of the C1-C6 alkyl bromide.
