Nanoparticulas de prata com área de superficie especifica e um métodos para a produção das mesma |
摘要 |
<p>Silver nanoparticles associated with 20 to 80% by weight of a biocomponent of the genus Lactobacillus, said silver nanoparticles having a ratio of the average particle size to the specific surface area (BET) of from 0.015 to 0.15 nm/m2/g; a method for producing silver nanoparticles, comprising the step of incubating bacteria of the genus Lactobacillus with an aqueous solution comprising at least 4 mM of a silver salt in the presence of ammonia and an alkali metal hydroxide until a biomass of bacteria containing Ag0 silver nanoparticles is formed; and optionally a further step of extracting said Ag0 silver nanoparticles from said biomass by means of concentrated alkali metal hydroxide or concentrated inorganic acid or enzymes; an anti-microbial composition comprising an effective amount of said silver nanoparticles; use of said silver nanoparticles for the manufacturing of an article or a composition with anti-microbial activity; a method for manufacturing an article or a composition with anti-microbial activity, comprising dispersing or impregnating said silver nanoparticles into said article or composition; and an article with anti-microbial property having said silver nanoparticles dispersed therein.</p> |
