  • Publication number: 20090010981
    Abstract: The invention relates to an antimicrobial material and method for inhibiting bacterial growth. The antimicrobial material may be used for implanting in bones and for coating or producing an implant or an implantable medical device, whereby particles formed from an antimicrobial material are remotely dispersed inside a matrix material that forms a matrix when hardened. In order to improve the compatibility of the antimicrobial material, the invention provides that the metal is formed from aggregates of primary particles having an average particle size ranging from 10 to 100 nm.
