Polypropylene mesh materials have been utilized in hernia surgery for over 40 years. However, they are prone to degradation due to the body’s aggressive foreign body reaction, which may cause pain or complications, forcing mesh removal from the patient. To mitigate these complications, gold nanomaterials were attached to polypropylene mesh in order to improve cellular response. Pristine samples of polypropylene mesh were exposed to hydrogen peroxide/cobalt chloride solutions to induce formation…

The increased oxidative stability corresponded to the greater free radical scavenging ability of the nanocomposites, and better biocompatibility was associated with the surface morphological change in the presence of Au.

Characterization of bionanocomposite scaffolds comprised of amine-functionalized gold nanoparticles and silicon carbide nanowires crosslinked to an acellular porcine tendon.

Investigation of two novel "bionanocomposite" materials in which either gold nanoparticles or silicon carbide nanowires were crosslinked to a porcine tendon resulted in scaffolds with improved resistance to enzymatic degradation and appropriate biocompatibility characteristics, thus warranting further study of these materials for soft tissue repair and tissue engineering applications.
