Modelos de membranas celulares y su interacción con nanopartículas magnéticas

Abstract

Esta Tesis Doctoral, de carácter multidisciplinar, versa sobre la fabricación de membranas celulares simuladas de fosfolípidos y colesterol. Se han buscado las condiciones para la obtención de películas superficiales muy homogéneas que permitan fácilmente analizar fenómenos superficiales inducidos por la presencia de otros elementos. A estas membranas biomiméticas se les ha incorporado también un glicoesfingolípido conteniendo un grupo azida. El grupo azida permite la realización de química bioortogonal (reacción con un grupo alquino terminal) para la deposición específica de nanopartículas magnéticas (MNPs) convenientemente funcionalizadas. Se ha analizado cómo un campo magnético alterno puede alterar la membrana celular cuando se han incorporado MNPs en su superficie. Se ha concluido que el campo magnético alterno induce un calentamiento local de la membrana decorada con MNPs, modificando su fluidez y generando poros en la misma. También se ha estudiado el efecto de la rugosidad del sustrato en las membranas celulares simuladas mediante un estudio topográfico de microscopía de fuerza atómica y un estudio nanomecánico mediante curvas de fuerzas. Se ha demostrado la influencia de la rigidez de un sustrato en la determinación del módulo de Young de una película blanda y se han aplicado modelos para la corrección de la presencia del sustrato.
