More Information
Summary:A flame spray pyrolysis method for producing a doped silica(SiO2) having antimicrobial and/or antibacterial and/or antifungal effect and being in the form of particles is disclosed. Said flame made doped silica comprises at least one functional dopant consisting of at least one antimicrobial and/or antibacterial and/or antifungal acting metal and/or metal-oxide, and is produced starting from a precursor solution comprising at least one functional dopant precursor, in particular a silver and/or copper comprising precursor, and at least one silica precursor in an organic solvent. Such doped silica is suitable for being incorporated within e.g. polymeric materials or for being used as impregnating material.
