We disclose a system for preparing antimicrobial surfaces, coated with metal oxide nanoparticles by means of a novel sonochemical method. These antibacterial surfaces are widely used in medical and other applications. The deposition of metal oxides known to possess antimicrobial activity, namely ZnO, MgO and CuO, can significantly extend the applications of textile fabrics, medical devices and other items and prolong the period of their use. By means of the novel sonochemical method disclosed here, uniform deposition of metal oxide nanoparticles is achieved simply.

Sonochemical coating of textiles with metal oxide nanoparticles for antimicrobial fabrics

Nanoparticle composites comprised of a metal oxide and ions of a metallic element included within a crystal lattice of said metal oxide are disclosed. Process of preparing the nanoparticle composites per se and incorporated in or on a substrate are also disclosed. Uses of the nanoparticle composites and of substrates incorporating same, particularly for reducing a formation of a load of a microorganism or of a biofilm, are also disclosed.

Doped metal oxide nanoparticles of and uses thereof

We disclose a system for preparing antimicrobial fabrics, coated with metal oxide nanoparticles by means of a novel sonochemical method. These antibacterial fabrics are widely used for production of outdoor clothes, under-wear, bed-linen, bandages, etc. The deposition of metal oxides known to possess antimicrobial activity, namely ZnO, MgO and CuO, can significantly extent the applications of textile fabrics and prolong the period of their use. By means of the novel sonochemical method disclosed here, uniform deposition of metal oxide nanoparticles is achieved simply.
