Tribological Characteristics of Al2O3 Nanocomposites for Joint Prostheses

Journal of Biomechanical Science and Engineering, 2008
In this study the tribological characteristics of a sliding pair of Al2O3 nanocomposites against Al2O3 were investigated. Al2O3 nanocomposites are proposed as a candidate material for the fabrication of prostheses.

Ti3C2T x ‐UHMWPE Nanocomposites—Towards an Enhanced Wear‐Resistance of Biomedical Implants

Journal of Biomedical Materials Research Part A, Volume 113, Issue 1, January 2025.
Polymeric biomedical materials, notably UHMWPE in load‐bearing joints, lack optimal mechanical and biotribological properties. This study aims to enhance Ti3C2T x ‐UHMWPE nanocomposites, improving mechanical strength, biocompatibility, and biotribological performance. Tests reveal no adverse effects on hardness, elasticity, or cytotoxicity.

Influence of Neutral and Cationic Phytoglycogen Nanoparticles on Cartilage and Ocular Lubrication

Biosurface and Biotribology, Volume 11, Issue 1, January/December 2025.
ABSTRACT Compromised hydration and biolubrication leads to untreatable disorders like osteoarthritis (OA), dry eye disease (DED) and dry mouth disease (xerostomia). Only symptomatic treatment is possible through bioactive molecules. This study aims to investigate the biolubrication properties of natural and modified phytoglycogen nanoparticles (PGNPs ...

In-situ generated tribomaterial in metal/metal contacts: Current understanding and future implications for implants

, 2017
[EN] Artificial hip joints operate in aqueous biofluids that are highly reactive towards metallic surfaces. The reactivity at the metal interface is enhanced by mechanical interaction due to friction, which can change the near-surface structure of the ...
