  • Publication number: 20170079264
    Abstract: The invention relates to an aqueous composition useful for producing antimicrobic polymer films, comprising at least an anionic silver complex, one or more cationic organic components with microbicidal activity, a solvent and a polymeric component. Said antimicrobic films can be obtained by depositing the aqueous composition of the invention on the surface to be treated, possibly followed by a thermosetting or photocuring treatment. The antimicrobic polymer films can be produced on surfaces of containers made of plastic, glass, ceramic or metallic material, thereby ensuring a barrier effect which protects the treated surface from invasions of external microbial agents borne by the air or hands of workers who use such containers.

  • Patent number: 8389022
    Abstract: A coating product composition has the general formula AOx-(L-Men+)i, wherein AOx is a metal or metalloid oxide in which x indicates the number of the Oxygen atom(s) (O) bonded to the metal (A) atom, Men+ is a metal ion, L is a bifunctional molecule that could bind both metal oxide or metalloid oxide (AOx) and the metal ion (Men+), i is the number of the (L-Men+) groups bound to the metal oxide AOx. The value of the parameter i depends on various factors, such as the size of the nanoparticle of AOx, and the nature of the molecule L.

  • Publication number: 20090270997
    Abstract: The present invention proposes novel materials and methods, for preparation of coatings based on titanium dioxide for osteointegrated biomedical prostheses. The coatings are realized with nanomaterials having antibacterial properties, and have the purpose of: promoting osteointegration of the implants, and, at the same time, reducing reaction attributable to inflammatory processes which derive from infections which may develop in the neighborhood of the implants.
