Resumen

Películas delgadas de silicato de bismuto (BSO) se han fabricado mediante el proceso sol-gel. El sol estable se sintetizó utilizando nitrato de bismuto (III) pentahidrato y tetraetil-ortosilicato (TEOS). Las películas fueron depositadas a 1500 rpm mediante la técnica de centrifugado. Los recubrimientos se caracterizaron por microscopía de fuerza atómica (AFM), microscopía electrónica de barrido (SEM), difracción de rayos-X (DRX) y se midió el espesor de las películas. El objetivo de este estudio fue evaluar la adhesión y la proliferación en células de osteoblastos, mediante el ensayo MMT, al incubarse sobre películas BSO en sustratos de 316L. Se concluyó que el crecimiento de los osteoblastos es homogéneo en la superficie de las películas, indicando que el medio ofrecido por los recubrimientos no presenta actividad citotóxica y favorece los niveles de crecimiento celular en comparación con los resultados obtenidos para los sustratos de acero inoxidable.
