| Abstract Scope |
Diamond-like carbon coatings are being evaluated for many types of biotechnology and biomedical applications due to their exceptional mechanical, chemical, and biological properties. We evaluated the adhesion, mechanical, chemical, and biocompatibility properties of silicon-incorporated diamond-like carbon coatings. The effects of argon and oxygen plasma treatments on coating adhesion were also examined. Silicon-incorporated diamond-like carbon coatings were deposited on fused silica using plasma enhanced chemical vapor deposition. The plasma-treated coatings showed greater hydrophilicility than the unmodified silicon-incorporated diamond-like carbon coating. Atomic force microscopy and profilometry studies showed that the plasma treatment increased coating roughness and coating roughness. The plasma treatment was also shown to reduce the adhesion of the coating. The unmodified and plasma-treated coatings were shown to be biocompatible. The results of this study indicate that plasma enhanced chemical vapor deposition produced diamond-like carbon coatings with appropriate adhesion, mechanical, chemical, and biocompatibility properties for biotechnology and biomedical applications. |
