Method of producing biocompatible metal nanoparticles from the platinum group, nanoparticles produced by this method and their application

摘要

The object of the invention is the production of Pt or Pd nanoparticles, or of Pt/Pd or Pt/Ag platinum alloys, comprising steps to reduce Pt or Pd precursors or to mix Pt/Pd precursors or to mix Pt/Ag precursors in an aqueous solution and then to purify the nanoparticles resulting from the reduction, in which the reduction in the aqueous solution of precursor Pd, Pt or a mixture of precursors Pt/Pd or a mixture of precursors Pt/Ag is achieved by the gradual addition of the diluent solution to the precursor solution(s), together with the addition of the glutathione solution. The result also concerns nanoparticles obtained in this way, nanoparticles, nanoparticles Pt or Pd,or Pt/Pd or Pt/Ag platinum alloys coated with glutaton, as well as nanoparticles for use as a medicine, including in cancer treatment.
