“…DLC films containing various amounts of titanium have been investigated to obtain a biocompatible surface and enhanced bony ingrowth. As Ti-DLC is exposed to biological surroundings, the adsorption of various proteins was related with the titanium contents in DLC film [25]. As widely believed, the adsorbed proteins will subsequently influence cell attachment, cell proliferation and cell differentiation.…”

“…Furthermore, DLC film is a spurious base coating to be alloyed with various elements. The properties of DLC film can be promoted to include certain amounts of additional elements, such as F, N, O, Cu, V, Ti, Ta and their combinations [25][26][27][28], into the films and still maintain the microstructure without any phase transformation. Among them, titanium is a biocompatible material.…”

“…As different applications of the diamond and DLC coating may require different surface properties, a number of studies have attempted surface modification by doping with additional elements. To test the influence of doping element, the DLC coatings were modified by phosphorus,11 silicon,12–14 nitrogen,15 fluorine16 and some metals 17, 18. The antifouling properties of boron‐doped diamond coatings have been detected in electroanalytical studies 19, 20…”

Protein-repellent diamond coatings have great potential value for surface coatings on implants and surgical instruments. The design of these coatings relies on a fundamental understanding of the intermolecular interactions involved in the adhesion of proteins to surfaces. To get insight into these interactions, adhesion energies of glycine to pure and Si and N-doped (111) diamond surfaces represented as clusters were calculated in the gas phase, using density functional theory (DFT) at the B3LYP/6-31G* level. The computed adhesion energies indicated that adhesion of glycine to diamond surface may be modified by introducing additional elements into the surface. The adhesion was also found to induce considerable change in the conformation of glycine when compared with the lowest-energy conformer of the free molecule. In the Si and N-substituted diamond clusters, notable changes in the structures involving the substituents atoms when compared with smaller parent molecules, such as 1-methyl-1-silaadamantane and 1-azaadamantane, were detected. Adhesion free energy differences were estimated for a series of representative peptides (hydrophobic Phe-Gly-Phe, amphiphilic Arg-Gly-Phe, and hydrophilic Arg-Gly-Arg) to a (111) diamond surface substituted with different amounts of N, Si, or F, using molecular dynamics simulations in an explicit water environment employing a Dreiding force field. The calculations were in agreement with the DFT results in that adsorption of the studied peptides to diamond surface is influenced by introducing additional elements to the surface. It has been shown that, in general, substitution will enhance electrostatic interactions between a surface and surrounding water, leading to a weaker adhesion of the studied peptides.

Diamondlike carbon thin films may provide next generation medical device surfaces with unique hardness, friction, wear, corrosion, and cell interaction properties. In the present paper, laser processing, mechanical properties, and medical applications for diamondlike carbon thin films are reviewed. Diamondlike carbon processing parameters are discussed, with emphasis given to novel techniques for improving diamondlike carbon film adhesion. Potential applications of diamondlike carbon thin films in biosensor, cardiovascular, orthopaedic, and microelectromechanical system (MEMS) devices are examined. Finally, future directions in diamondlike carbon thin film research are presented.
