Beschreibung
Zusammenfassung:	The present invention relates to a contact lens coated with chitosan nanoparticles thiolated with silver nanoparticles to prevent and aid eye infections. The synthesis of the components and their interaction form a functional system based on a silicone lentil functionalized with thiolated chitosan (QS-SH) and silver nanoparticles (AgNPs), characterizing the physicochemical properties of the components separately (QS film and AgNPs). Said analyses allow expecting the end product to be viable and, due to the techniques used, to foresee a process of easy scalability and low cost. La presente invención consiste en una lentilla de contacto recubierta de nanopartículas de quitosano tiolado con nanopartículas de plata para prevenir y auxiliar infecciones oculares. Se realizo el protocolo de síntesis de los componentes y de su interacción para conformar un sistema funcional a base de una lentilla de silicona funcionalizada con quitosano tiolado (QS-SH) y nanopartículas de plata (AgNPs). Se caracterizaron las propiedades fisicoquímicas de los componentes por separado (película de QS y AgNPs). Los análisis realizados nos permiten esperar que el producto final sea viable y debido a las técnicas usadas podemos prever un proceso de fácil escalabilidad y costo bajo.
