Silver-doped diamond-like carbon: towards highly stable antibacterial coatings

Silver doped perfluoropolyether-urethane coatings: antibacterial activity and surface analysis.

The colonisation of clinical and industrial surfaces with pathogenic microorganisms has prompted increased research into the development of effective antibacterial and antifouling coatings. There is evidence that implanted biomedical surfaces coated with metallic silver can be inactivated by physiological fluids, thus reducing the bioactivity of the coating. In this work, we report the biofilm ...

Ultrasonic characterization of mechanical properties of Cr- and W-doped diamond-like carbon hard coatings

Two ultrasonic nondestructive evaluation methods have been applied to systematically characterize the mechanical properties of nanostructured physical vapor deposited diamond-like carbon (DLC) ultra-hard coatings. A photoacoustic guided-wave technique is used to generate broadband surface acoustic waves (SAW) on the coating surfaces, and dispersion relations of the SAW for DLC coatings are meas...

AlTiN layer effect on mechanical properties of Ti-doped diamond-like carbon composite coatings

Antibacterial potency of different deposition methods of silver and copper containing diamond-like carbon coated polyethylene

BACKGROUND Antibacterial coatings of medical devices have been introduced as a promising approach to reduce the risk of infection. In this context, diamond-like carbon coated polyethylene (DLC-PE) can be enriched with bactericidal ions and gain antimicrobial potency. So far, influence of different deposition methods and ions on antimicrobial effects of DLC-PE is unclear. METHODS We quantitati...

Diamond-Like-Carbon Coatings for Advanced Biomedical Applications

Diamond-like carbon (DLC) is considered as a versatile coating material that finds a variety of mechanical and biomedical applications, including endoprosthesis and dental implants [1]. It provides mechanical robustness and cell-compatibility at the same time. Therefore, DLC has been extensively researched for achieving high hardness, low friction, high wear resistance to make it more sustainab...
