Title
(EN) METHOD AND COMPOSITION FOR PATHOGEN INHIBITION UTILIZING ENGINEERED CRYSTALLINE STRUCTURES
(FR) PROCÉDÉ ET COMPOSITION D’INHIBITION DE PATHOGÈNE UTILISANT DES STRUCTURES CRISTALLINES MODIFIÉES
Abstract
(EN) An engineered crystalline structure created from a solution containing silica dioxide that is applied on a surface and dries forming a barrier coating on the treated surface. The formed of the barrier coating has proven to be an effective antimicrobial barrier solely with inert ingredients. Moreover, the established barrier has been shown to eradicate SARS-CoV-2 within two hours without chemical intervention. When applied to a surface and allowed to dry, a 4-6 nm crystalline-like layer of silica dioxide bonds covalently to the surface. The crystalline-like structures making up the "new" surface are invisible to the naked eye but can be observed via a high-powered electronic microscope. Once silica dioxide is applied to a surface, the crystalline-like structures contain spikes that penetrate the outer membranes and protein coats of microorganisms, rendering them dead in the case of bacteria and fungi or inactive in the case of viruses.
(FR) Une structure cristalline modifiée créée à partir d’une solution contenant du dioxyde de silicium qui est appliquée sur une surface et sèche un revêtement formant barrière sur la surface traitée. La formation du revêtement formant barrière s’est avérée comme étant une barrière antimicrobienne efficace uniquement avec des ingrédients inertes. En outre, il a été démontré que la barrière établie éradique le SARS-CoV-2 en deux heures sans intervention chimique. Lorsqu’appliquée à une surface et laissée à sécher, une couche de type cristallin de 4 à 6 nm de dioxyde de silicium se lie de manière covalente à la surface. Les structures de type cristallin constituant la "nouvelle" surface sont invisibles à l’œil nu mais peuvent être observées par l’intermédiaire d’un microscope électronique à haute puissance. Une fois que le dioxyde de silicium est appliqué à une surface, les structures de type cristallin contiennent des pointes qui pénètrent les membranes externes et les manteaux protéiques des micro-organismes, les tuant dans le cas des bactéries et des champignons ou les inactivant dans le cas des virus.
