Actividad biocida de vidrios sodocálcicos que contienen nanopartículas de plata o cobre

Abstract

[EN] Silver and copper nanoparticles dosers composed by soda-lime glasses have been developed with biocide properties for mediambiental and biomedical applications. It has been proved that these glasses are perfect nanoparticles dosers due to the slow releasing of such nanoparticles keeping their concentration below the toxic limit. The biocide activity was sutudied against different microorganisms (gram-negative bacteria, gram-positive bacteria and yeasts) obtaining high activity against all of them. Finally, low cost materials (sepiolite, montmorillonite, kaolin and diatoms) were used as nanoparticles carriers. [ES] Se han desarrollado dosificadores de nanopartículas de cobre y de plata compuestos por vidrios sodocálcicos con propiedades biocidas para aplicaciones medioambientales y biomédicas. Se ha probado que estos vidrios son perfectos dosificadores de nanopartículas ya que liberan lentamente dichas nanopartículas manteniendo la concentración de nanopartículas por debajo del límite de toxicidad. También se ha evaluado su actividad biocida frente a diferentes microorganismos (bacterias gram-negativas, gram-positivas y levaduras) obteniéndose una elevada actividad biocida frente a todos ellos. Por último, se utilizaron como portadores de nanopartículas materiales de bajo coste (sepiolita, montmorillonita, caolín y diatomeas).

Tesis elaborada en el Dpto. de Biomateriales y Materiales Bioinspirados del Instituto de Ciencia de Materiales de Madrid y presentada en el Dpto. de Química Inorgánica de la Facultad de Ciencias de la Universidad Autónoma de Madrid en 2012, para optar al grado de Doctor en Química.
