摘要

摘要本研究报道了一类基于组合物ICIE16的硼掺杂生物活性玻璃的溶解研究。在静态和动态条件下，使用模拟体液（SBF）、Tris缓冲溶液和乳酸作为溶解介质进行研究。比较了在所评估的条件和介质下从玻璃中浸出离子的情况，并评估了玻璃的生物活性行为。还分析了硼的掺入对玻璃热性能的影响。与静态条件相比，玻璃在动态溶解配置下表现出更快的生物活性。此外，玻璃在酸性条件下的溶解速率比在SBF或Tris溶液中更快。研究发现，随着硼含量的增加，玻璃的溶解速度更快。

Bioactivity and dissolution behavior of boron-containing bioactive glasses under static and dynamic conditions in different media

Abstract The present study reports the dissolution studies of a family of boron-doped bioactive glasses based on the composition ICIE16. Simulated body fluid (SBF), Tris-buffered solution and lactic acid were used as dissolution media for studies under static and dynamic conditions. The leaching of ions from the glasses under the evaluated conditions and media was compared and the bioactive behaviour of the glasses was evaluated. Influence of the incorporation of boron in the thermal properties of the glass was also analysed. Glasses exhibited faster bioactivity under dynamic dissolution configuration compared to static conditions. Moreover, the glass dissolution rate was faster in acidic conditions than in SBF or Tris solutions. It was found that at increasing boron content the dissolution of the glass is faster.
