Lecture: Antibacterial equipment of implant materials by means of atmospheric pressure plasmas.

Abstracts:

The range of materials used in medicine today covers almost all material groups. Special plastics are used for wound dressings or stents, while ceramics and metal alloys are widely used as implant materials. Additional coating steps are often necessary to increase the biocompatibility of these materials, for example, to ensure that the implants grow into human tissue. On the other hand, additional antibacterial finishes are often necessary so that the risk of infection is reduced to a minimum.
For subsequent modification or functionalization, coating by means of atmospheric pressure plasmas represents a tool with many possibilities in this respect. By using appropriate starting materials and processing parameters, nanocomposite layers can be deposited with this technology, whereby various metallic active agent media based on Ag, Cu or Zn can be used. In addition to studies on the deposition of these layers and the associated layer analysis, the presentation will focus on the evaluation of the antibacterial potential, combined with the cytotoxic properties.
