The invention relates to nanoparticles, comprising a support and a coating of a polymer material. The polymer material comprises functional groups, to which reversible metal ions are bonded. Said nanoparticles may be incorporated in plastics and workpieces may be produced from the obtained compounds, which are particularly suitable for medical applications. The workpieces for example, drainage tubes, or inner coatings of medical devices, give off small amounts of metal ions in contact with body fluids which have an anti-microbial or bacteriostatic effect. On longer application the penetration of disease-inducing agents is effectively suppressed. |
