Title (EN) NANOSTRUCTURED CALCIUM-SILVER PHOSPHATE COMPOSITE POWDER, METHOD FOR OBTAINING SAME, AND BACTERICIDAL AND FUNGICIDAL USES THEREOF
(ES) POLVO COMPUESTO NANOESTRUCTURADO FOSFATO DE CALCIO-PLATA. PROCEDIMIENTO DE OBTENCIÓN Y SUS APLICACIONES BACTERICIDAS Y FUNGICIDAS
(FR) COMPOSÉ DE POUDRE NANOSTRUCTURÉ DE PHOSPHATE DE CALCIUM-ARGENT. PROCÉDÉ D'OBTENTION ET SES APPLICATIONS BACTÉRICIDES ET FONGICIDES
Abstract:
(EN) The invention relates to a nanostructured calcium-silver phosphate composite powder which can be used as a bactericide and/or fungicide, with similar effectiveness to that of commercial products and with low toxicity. The invention also relates to a method for obtaining said nanostructured calcium-silver phosphate composite powders, which comprises preparing nanometric calcium phosphate by means of a sol-gel process and subsequently depositing silver nanoparticles on the surface thereof. Said nanostructured powder can be used for the production of a bactericide and/or fungicide composition suitable for use as an all-purpose disinfectant to be used, for example, in surgical implants, public facilities, food, dentistry, paints, clothes and packaging.
(ES) La presente invención lo constituye un polvo compuesto nanoestructurado fosfato de calcio-plata útil como antibactericida y/o fungicida, con una eficacia similar a la de productos comerciales y con una baja toxicidad. El segundo objeto de la presente invención lo constituye el procedimiento de obtención de dichos polvos compuestos nanoestructurados fosfato de calcio- plata, consistente en la preparación de fosfato de calcio nanométrico a partir de un procesamiento sol-gel y, a continuación, la deposición de nanopartículas de plata en su superficie. Este polvo nanoestructurado puede ser utilizado en la elaboración de una composición bactericida y/o fungicida útil como desinfectante universal para aplicaciones, por ejemplo, en implantes quirúrgicos, instalaciones de uso público alimentación, dental, pinturas, prendas de vestir y embalajes.
(FR) La présente invention concerne un composé de poudre nanostructuré de phosphate de calcium-argent qui convient comme bactéricide et/ou fongicide, avec une efficacité similaire à celle de produits du commerce et avec une toxicité faible. Le second objet de la présente invention concerne le procédé d'obtention desdits composés de poudre nanostructurés de phosphate de calcium-argent, qui consiste à préparer le phosphate de calcium nanométrique à partir d'un processus sol-gel et, ensuite, à déposer des nanoparticules d'argent à sa surface. Cette poudre nanostructurée peut-être utilisée dans l'élaboration d'une composition bactéricide et/ou fongicide qui convient comme désinfectant universel pour des applications, par exemple, dans des implants chirurgicaux, des installations à usage public, dans l'alimentation, le domaine dentaire, les peintures, les vêtements et les emballages.
