Development of antibacterial MetAllic Glass mICrofibers

Descripción del proyecto

Nuevas microfibras antibacterianas de vidrios metálicos

La causa principal por la que los implantes metálicos fallan es la infección por la formación de biopelículas bacterianas en su superficie. El proyecto MAGIC, financiado con fondos europeos, propone desarrollar vidrios metálicos de Zr-Cu-Ag con propiedades antibacterianas intrínsecas y que no necesiten un revestimiento adicional. Para desarrollar esta nueva clase de metales, es necesario conocer su mecanismo antibacteriano. El objetivo primordial del proyecto es descubrir el mecanismo antibacteriano subyacente de estos innovadores vidrios metálicos de Zr-Cu-Ag a través de un enfoque interdisciplinario novedoso en el que se combina la construcción de materiales con un análisis biológico avanzado de las bacterias. El proyecto tiene por objeto fabricar el mejor vidrio metálico de Zr-Cu-Ag en forma de microfibras como prueba de concepto para la aplicación de vidrios metálicos antibacterianos en la industria médica.

Objetivo

The proposed training-through-research aims to develop novel antibacterial materials for medical devices based on Zr-Cu-Ag metallic glasses in the form of microfibers. The major cause of metal implants retrieval is infection due to bacterial biofilm formation on their surface. Many studies have been conducted on the development of antibacterial coating on metallic implants, but evidence has shown numerous drawbacks associated with coatings including their lack of durability. “MAGIC” project proposes the development of Zr-Cu-Ag metallic glasses with generic and intrinsic antibacterial properties which makes them capable of battling antibiotic resistance bacterial infection with no further required coating. Meaningful development of this novel class of intrinsic antibacterial metals requires a fundamental understanding of their antibacterial mechanism which to date is not well-understood. Therefore, “MAGIC” project fundamental ambition is to discover the underlying antibacterial mechanism of innovative Zr-Cu-Ag metallic glasses though a novel interdisciplinary approach, combing materials engineering knowledge of metallic glasses with advanced biological analysis of bacteria. On the engineering side, the main antibacterial contributors “chemical composition” and “surface energy” of Zr-Cu-Ag metallic glass will be modified and controlled; On the biological analysis side, bacterial genetic and metabolic response to these changes will be studied by coupling basic metabolic assays with next-generation sequencing and omics techniques. Furthermore, to facilitate the integration of antibacterial metallic glasses in the medical industry, “MAGIC” has an applied ambition to fabricate the best found Zr-Cu-Ag metallic glass (in terms of chemical composition and surface energy) in the form of microfibers for the very first time. Microfibers have higher surface areas and are easier to be formed into different shapes, offering added value to their applicability in industry.
