    A molecular dynamics modelling adsorption study of Cu and Ag nanoparticles on pristine and functionalized graphene surfaces

    No full text
    The overuse of antibiotics has led to the flourishment of antibiotic-resistant bacteria and consequently to the need to develop new, more efficient pharmacological compounds. It is well known that graphene oxide (GO) doped with metallic particles exhibits broad-spectrum antimicrobial activity. In addition, in order to improve the pharmacokinetic behavior of these compounds and their solubility in biological media, polyethylene glycol (PEG) is attached to the graphene surface. Among the different available characterization techniques, molecular dynamics simulations (MD) deserve special attention, as they allow the study of different materials from a molecular point of view. In this work, MD simulations of the adsorption of small Ag and Cu clusters on pristine graphene and PEGylated graphene oxide (GO_PEG) surfaces were carried out. The results are presented in terms of adsorption energies, mean equilibrium distances between nanoparticles and graphene surfaces, radial distribution functions and diffusion coefficients of the metallic nanoclusters. These preliminary results show that PEGylation of the surface is critical to strengthen the interaction between the surfaces and the metallic clusters, which, in turn, is a key factor for improving the efficacy of these compoundsUEM1915No data JCR 20200.341 SJR (2020) Q3, 306/638 Materials Science (miscellaneous)No data IDR 2019UE

    Modelling the interaction between graphene surfaces and metallic nanoclusters

    The overuse of antibiotics has led to the flourishment of antibiotic-resistant bacteria [1] and consequently to the need to develop new, more efficient pharmacological compounds. Several advanced materials are being studied, among which are metallic nanoparticles and certain graphene oxides (GO) modified with polyethylene glycol (PEG) [2-4]. In this work, molecular dynamics (MD) simulations of the adsorption of small Ag and Cu clusters on pristine graphene and PEGylated graphene oxide (GO_PEG) surfaces were carried out. The results are presented as a function of nanoparticles concentration, adsorption energies, mean equilibrium distances between nanoparticles and graphene surfaces (figure 1), radial distribution functions and diffusion coefficients of the metallic nanoclusters. These preliminary results show that PEGylation of the surface is critical to strengthen the interaction between the surfaces and the metallic clusters, which, in turn, is a key factor for improving the efficacy of these compounds.Sin financiaciónNo data 2020UE

    En este trabajo se describe una experiencia piloto realizada con alumnos de 1º y 2º de los Grados de Farmacia, del Doble Grado de Farmacia y Biotecnología y del Doble Grado de Farmacia y Óptica. Dicha experiencia consiste en la realización de varias actividades que requieren del uso de dispositivos móviles y que cubren diferentes aspectos del aprendizaje. El objetivo es orientar su empleo a cuestiones académicas, aprovechando la popularidad de dichos dispositivos y la buena disposición que el alumno muestra a usarlos. Para valorar el resultado de esta actividad, se analizaron de modo cuantitativo, las respuestas de alumnos a un cuestionario. Entre los principales resultados obtenidos se extrae que el estudiante percibe que este tipo de actividades son una forma innovadora y atractiva para mejorar su aprendizaje. El manejo de las aplicaciones le resulta sencillo y se muestra predispuesto a continuar empleándolas con fines didácticos.SIN FINANCIACIÓNNo data 2012UE
