Plasma mediated collagen‐I‐coating of metal implant materials to improve biocompatibility

Journal of Biomedical Materials Research Part A, 2010
AbstractThis study describes the collagen‐I coating of titanium and steel implants via cold low‐pressure gas plasma treatment. To analyze the coatings in terms of biocompatibility osteoblast‐like osteosarcoma cells and human leukocytes were cultivated on the metal surfaces.

Diamond-like carbon coatings as biocompatible materials—an overview

Diamond and Related Materials, 2003
Amorphous hydrogenated diamond-like carbon (DLC) and tetrahedral carbon (taC) films are characterized by high wear resistance, low friction coefficients and chemical inertness, thus high-corrosion resistance. The properties of DLC and taC can further be modified by incorporating other elements in the films, such as N, F, Si and metals, thus tailoring ...

Plasma Surface Fluorination of Hydrogel Materials—Coating Stability andin vitroBiocompatibility Testing

Soft Materials, 2010
Plasma enhanced chemical vapor deposition has been tested for the formation of hydrophobic perfluorinated coating on the surface of hydrophilic poly(2-hydroxyethyl methacrylate-co-methyl methacrylate) [poly(HEMA-co-MMA)] substrates, used for the fabrication of intraocular lenses (IOLs).

Sequential Solid-Phase Microextraction with Biocompatible Coating Materials to Address Displacement Effects in the Quantitative Analysis

Analytical Chemistry, 2023
Solid-phase microextraction (SPME) is a simple and effective sample-preparation technique for the analysis of complex samples. However, sample matrices containing high concentrations of nonpolar substances or spiked analytes in free form can cause swelling, saturation, and/or competition phenomena in the coating material. This results in a displacement

Biocompatibility improvement of titanium implants by coating with hybrid materials synthesized by sol-gel technique.

Journal of biomedical materials research. Part A, 2014
Organic-inorganic hybrid materials based on zirconia and polyethylene glycol (PEG) have been synthesized via sol-gel method in the present study. Those materials, still in the sol phase, have been used to coat a titanium grade 4 (Ti-4) substrate to improve its biological properties. Dip-coating technique has been used to obtain thin films.

Enhanced biocompatibility of CoCr implant material by Ti coating and micro‐arc oxidation

Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2008
AbstractThe biocompatibility of CoCr alloy was significantly improved by forming a rough TiO2 layer on its surface. The TiO2 layer was formed by coating the CoCr alloy with titanium (Ti) through electron beam deposition followed by microarc oxidation (MAO). When Ti was coated on the surface, the biocompatibility of the CoCr alloy was enhanced and it

Surface Properties of Biocompatible Calcium-Silicon-Phosphate Glass Ceramic Materials and Coatings

Glass and Ceramics, 2017
The influence of the surface properties of the developed calcium-silicon-phosphate glass ceramic materials and coatings on biocompatibility is determined. The calcium to phosphorus ratio on the surface of materials and coatings for forming an apatite-like layer on them as well as the optimal values of the roughness parameter and free surface energy for

Titanium Implant Materials with Improved Biocompatibility through Coating with Phosphonate‐Anchored Cyclic RGD Peptides

ChemBioChem, 2005
AbstractOne key point for improving osseous integration of implants is to render them osteopromotive by specifically favoring the adhesion of osteoblasts. Mimicking the physiological adhesion process of osteoblasts to the extracellular matrix improves cell adhesion in vitro and results in improved and earlier osseous integration of implants in vivo ...

High-quality hydroxyapatite coating on biocompatible materials by laser-assisted laser ablation method

Applied Physics A, 2004
A new method for high-quality hydroxyapatite (HAp) coating is developed, the laser-assisted laser ablation method. In this method, two lasers are used. One is used for ablation of a HAp target. The other, the assist laser, is used to irradiate a Ti substrate surface.
