J Appl Biomater Funct Mater:壳聚糖涂层达到药物缓释的效果

2017-11-26 MedSci MedSci原创

生物活性玻璃已经引起了骨科医生的极大兴趣,但是作为一种药物载体却鲜有研究。本研究旨在探究生物活性13-93B0和13-93B3玻璃牛血清白蛋白(BSA)的释放效果。生物活性玻璃(13-93B0和13-93B3; n = 5)装载4mg的BSA,并在不同的壳聚糖涂覆条件下涂覆壳聚糖。评估磷酸盐缓冲盐水(PBS)中释放的BSA的量,并进行降解研究以探究载体的重量损失和PBS的pH值。使用傅里叶变换红外

生物活性玻璃已经引起了骨科医生的极大兴趣,但是作为一种药物载体却鲜有研究。本研究旨在探究生物活性13-93B0和13-93B3玻璃牛血清白蛋白(BSA)的释放效果。

生物活性玻璃(13-93B0和13-93B3; n = 5)装载4mg的BSA,并在不同的壳聚糖涂覆条件下涂覆壳聚糖。评估磷酸盐缓冲盐水(PBS)中释放的BSA的量,并进行降解研究以探究载体的重量损失和PBS的pH值。使用傅里叶变换红外(FTIR)光谱对13-93B0上BSA的二级结构进行表征。

结果显示,对于所有13-93B3组,24小时内BSA达到了100%的释放。然而,在13-93B0组中,壳聚糖涂层延迟了BSA释放达72小时。无论壳聚糖涂层状态如何,13-93B3玻璃的降解速率均高于13-93B0。多层和三明治壳聚糖涂层进一步延迟了13-93B0 对BSA的释放。 FTIR分析显示,2%夹心壳聚糖涂覆组α-螺旋结构最高,且明显明显高于未涂覆壳聚糖和涂覆4%壳聚糖组(32.0%±2.1%)。

综上所述,该研究结果表明,壳聚糖涂层可延缓BSA从13-93B0玻璃的突释,并可成为生物活性玻璃上药物输送的涂层进行应用。
