En este trabajo se demuestra la capacidad del proceso sol-gel en la obtenci\u00f3n de materiales con diferentes fases, usando la misma composici\u00f3n qu\u00edmica, y modificando \u00fanicamente las condiciones de hidr\u00f3lisis y condensaci\u00f3n. Este m\u00e9todo combinado con la t\u00e9cnica de r\u00e9plica de esponja polim\u00e9rica permiti\u00f3 obtener un andamio poroso y tridimensional, llamado n\u00facleo, constituido principalmente por fases de fosfatos de calcio. Adicionalmente, debido a la versatilidad del proceso sol-gel, este n\u00facleo fue recubierto con fases adicionales,\u00a0constituidas por silicio y magnesio, obteniendo andamios multicapa. Los andamios fueron caracterizados f\u00edsica y qu\u00edmicamente y la bioactividad in vitro evaluada mediante inmersi\u00f3n en suero fisiol\u00f3gico artificial. Los resultados de bioactividad in vitro mostraron que el n\u00facleo revel\u00f3 una microestructura lamelar con algunos precipitados de apatito despu\u00e9s de 14 d\u00edas, mientras que los andamios multicapa presentaron precipitados sobre la superficie en solo 3 d\u00edas. La bioactividad acelerada y las propiedades generales del andamio multif\u00e1sico y multicapa, demuestran el potencial de este material en el \u00e1rea de ingenier\u00eda de tejido.<\/p>\n
