Antibacterial efficacy of ultrahigh molecular weight polyethylene with silver containing diamond-like surface layers

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...

Improved Wear Performance of Ultra High Molecular Weight Polyethylene Coated with Hydrogenated Diamond like Carbon

In vitro studies of multiwalled carbon nanotube/ultrahigh molecular weight polyethylene nanocomposites with osteoblast-like MG63 cells.

Carbon nanotubes are highly versatile materials; new applications using them are continuously being developed. Special attention is being dedicated to the possible use of multiwalled carbon nanotubes in biomaterials contacting with bone. However, carbon nanotubes are also controversial in regards to effects exerted on living organisms. Carbon nanotubes can be used to improve the tribological pr...

Synthesis of high molecular weight polyethylene using FI catalyst

A FI Zr-based catalyst of bis[N-(3,5-dicumylsalicylidene)-2′,6′­diisopropylanilinato]zirconium(IV) dichloride was prepared and used for polymerization of ethylene. The effects of reaction conditions on the polymerization were examined in detail. The increase in ethylene pressure and rise in polymerization temperature up to 35 oC were favorable for catalyst/MAO to raise the catalytic activity as...

Preparation of Antibacterial Silver Containing Nanocomposites

Silver containing nanocomposites receive increasing attention as antibacterial coatings. In this study we report on production of such materials using combination of gas aggregation sources of Ag nanoparticles and plasma enhanced chemical vapour deposition performed in HMDSO/O2 working gas mixtures. The main attention is devoted to the investigation of solubility of Ag nanoparticles in water in...
