Abstract

Procédé de traitement antimicrobien utilisant un dispositif comprenant un réseau percolant de nanofils, et produit comprenant le dispositif L’invention concerne un procédé (2) de traitement antimicrobien utilisant un dispositif (1) comprenant un réseau percolant de nanofils (100), les nanofils (100) étant à base d’au moins un matériau métallique, et les nanofils (100) étant recouverts d’une couche de protection (101) destinée à être en contact avec un milieu environnant (4) comprenant des microbes (40), et au moins une électrode électriquement connectée au réseau de nanofils (10) ; le procédé comprend au moins une alimentation en courant électrique du réseau de nanofils (100) par une source d’alimentation, pour chauffer par effet Joule le réseau de nanofils (100) de façon à provoquer la migration d’espèces (100’) issues du matériau métallique depuis les nanofils (100), à travers la couche de protection (101), et leur libération dans le milieu environnant (4). Figure pour l’abrégé : Fig.2Antimicrobial treatment method using a device comprising a percolating network of nanowires, and product comprising the device The invention relates to a method (2) for antimicrobial treatment using a device (1) comprising a percolating network of nanowires (100), the nanowires ( 100) being based on at least one metallic material, and the nanowires (100) being covered with a protective layer (101) intended to be in contact with a surrounding environment (4) comprising microbes (40), and at least one electrode electrically connected to the nanowire array (10); the method comprises at least one supply of electrical current to the network of nanowires (100) by a power source, to heat the network of nanowires (100) by Joule effect so as to cause the migration of species (100') from metallic material from the nanowires (100), through the protective layer (101), and their release into the surrounding environment (4).
