Nanoparticles improve properties of implants
04/06/2006

The Laser Zentrum Hannover e. V. (LZH) is currently carrying out research activities with the objective of better adapting implants to the human body. By applying laser-generated nanoparticles onto or into implants or medical devices, special functions can be provided or material properties improved.

The nanoparticles are generated using a laser-based procedure. What is so special about these particles is that they unfold their properties in the body without limiting the medical suitability and approvability of the product.

Silver, for instance, has antibacterial properties. Using silver nanoparticles on the surface of implants can decrease the risk of infections considerably. Other nanoparticles of high-strength ceramics increase the hardness or abrasion resistance of the implant material and contribute to the prevention of osteolysis, the dissolution or degeneration of bone tissue. It is also conceivable that nanoparticles of calcium phosphate are embedded to support the adherence of natural bone matter.

Nanoparticles are also suited to be used with heart valves, such as:

  • Silver nanoparticles for an antibacterial effect
  • Polymer nanoparticles for smoother surfaces
  • Metallic nanoparticles as contrast agents for function monitoring

In addition, nanoparticles can improve considerably or complement the properties of surgical instruments and other medical products.

To illustrate the size: 2,500,000,000 nanoparticles fit on the period at the end of this sentence.
