Abstract

La invención se refiere a un proceso para la preparación de una nanopartícula de fosfato cálcico amorfo recubierta de citrato que comprende las siguientes etapas: 1) proporcionar una primera solución de una sal de calcio y una sal de citrato en la que la relación molar de ión citrato a ión calcio está en el intervalo de 1 a 2 obteniendo así una primera solución transparente; 2) proporcionar una segunda solución de una sal capaz de dar un anión fosfato y una sal carbonato; 3) mezclar la primera y la segunda solución a un pH en el rango de 8 a 11; 4) precipitar la nanopartícula; y 5) secar la nanopartícula obtenida en el paso 4). Preferible y ventajosamente, la invención prevé la adición de un compuesto de fluoruro en la etapa 2) para obtener una nanopartícula de fosfato cálcico recubierto con citrato dopado con flúor o un aglomerado de nanopartículas. El aglomerado nanopartícula / nanopartícula de la invención tiene un área superficial peculiar y un diámetro que permiten utilizarlo como biomaterial para aplicación en odontología.
