Temperature effect on the porosity of hydroxyapatite scaffolds and its use in tissue engineering

The search for a suitable bone replacement is of great importance due to the difficulty to use autologous transplants. Hence, the objective of this work is to compare the temperature effect on the porosity and average pore diameter of hydroxyapatite porous scaffolds fabricated by the salt leaching m...

Hence, the objective of this work is to compare the temperature effect on the porosity and average pore diameter of hydroxyapatite porous scaffolds fabricated by the salt leaching method.  Hydroxyapatite porous scaffolds fabricated by the salt leaching technique were sintered from ~150 to 1000 °C. Synthesized hydroxyapatite was assessed by X-ray diffraction (XRD). Zeta potential at different temperatures was evaluated. Specimens were characterized using scanning electron microscopy (SEM) and Raman analysis. The results showed that significant porosity (57%) and pore size (49 µm) occurred with a thermal treatment above ~ 850 °C for scaffolds that were pre-sintered at 1050 °C. La búsqueda de un reemplazo óseo adecuado es de gran importancia debido a la dificultad de utilizar trasplantes autólogos. Es por esto, que el objetivo de este trabajo es comparar el efecto de la temperatura sobre la porosidad y el diámetro promedio de poro fabricados con el método de lixiviación de sales, siendo sinterizados desde ~150 a 1000 °C. Los andamios fabricados de hidroxiapatita fueron evaluados con difracción de rayos X (XRD). El potencial zeta fue evaluado a diferentes temperaturas. Los especímenes fueron caracterizados utilizando microscopia electrónica de barrido (SEM) y análisis Raman. Los resultados mostraron que la porosidad importante (57%) y tamaño de poro (49 µm) ocurren con un tratamiento térmico superior a ~ 850 °C para andamios que fueron pre-sinterizados a 1050 °C.
