NANOSTRUCTURED CALCIUM-SILVER PHOSPHATE COMPOSITE POWDER, PROCESS FOR OBTAINING SAID POWDER AND BACTERICIDAL AND FUNGICIDAL APPLICATIONS THEREOF

摘要

The present invention consists of a nanostructured calcium-silverphosphate composite powder which can be used as an antibactericide and/orfungicide, with a similar effectiveness to that of commercial products and lowlevel of toxicity. The second object of the present invention consists of theprocess for obtaining said nanostructured calcium-silver phosphate compositepowder, consisting of preparing nanometric calcium phosphate by means of asol-gel process and then depositing silver nanoparticles on the surfacethereof.This nanostructured powder can be used in the preparation of a bactericideand/or fungicide which can be used as a universal disinfectant forapplications,for example, in surgical implants, public facilities (toilets and hospitals,transport, etc.), food, dentistry, paints, clothes and packaging (food,pharmaceutical, medical devices).
