Abstract
The invention relates to a medicotechnical product having an antimicrobial finish consisting of a complex material of metal nanoparticles and macromolecules, the macromolecules being at least partially formed from amphiphilically modified polyamino acids which contain amino acid units, which aside from the functional groups bonded in the peptide bond contain at least one further functional group and at least some of these groups are modified with substances bearing hydrophobic radicals via covalent bonds. The hydrophobic radicals are bonded by addition of substances bearing epoxy groups to the at least one further functional group and/or via at least one amino group of an amino acid unit bearing at least one amino group as a further functional group with maintenance of an amino function on the polyamino acids. The invention furthermore relates to the production of the complex material and of the medicotechnical product.
