Anti-biofilm forming structure and method of manufacturing the same

A method for extending the biocidal properties of a bioresistant fluid handling system comprising at least one structural component adapted to retain or deliver fluid, the at least one structural component formed from a bioflim resistant material and an inorganic carrier conjugated with a biocidal metal ion, wherein when a surface of the at least one structural component is exposed to a continuous or intermittent aqueous solution environment, the formation of active biofilm on the surface is prevented and planktonic bacteria in proximity of the surface is killed, the method comprising:

• replenishing the biocidal metal ion that is exhausted from the biofilm resistant material by continuously or periodically introducing the biocidal metal ion, selected from the group consisting of at least silver, copper and zinc ions, into the contents of the aqueous solution environment resulting in equilibrium of biocidal metal ion exchange between the bioflim resistant material of the handling system and the aqueous solution environment.

A method for imparting extended biocidal properties to a dental water handling system comprising the steps of:

• providing at least one structural component adapted to retain or deliver dental water, wherein the at least one structural component is formed from a bioflim resistant material comprising a polymeric resin and an inorganic carrier conjugated with at least one biocidal metal ion that acts to prevent the formation of active bio film on the surface of the structural component and to kill planktonic bacteria in proximity of the surface when in contact with the dental water;
• and
• contacting the bioflim resistant material with dental water comprising the biocidal metal ion, whereby biocidal metal ion exchange between the biofilm resistant material and the dental water replenishes biocidal metal ion exhausted from the biofilm resistant material.

A method for extending the biocidal properties of a biofilm resistant fluid handling system comprising at least one structural component adapted to retain or deliver fluid, the at least one structural component formed from a bioflim resistant material comprising polymeric resin and an inorganic carrier conjugated with a biocidal metal ion, wherein when a surface of the at least one structural component is exposed to a continuous or intermittent aqueous solution environment, the formation of active bioflim on the surface is prevented and planktonic bacteria in proximity of the surface is killed, the method comprising;

• affixing a solvent, comprising an inorganic carrier conjugated with a biocidal metal ion, to the surface of the at least one structural component;
• wherein the surface is smoothed and the inorganic carrier conjugated with a biocidal metal ion is deposited into crevices on the surface thus preventing biofilm growth in the crevices which are desirable for bacteria colonization.
