Mater Sci Eng C Mater Biol Appl:酸碱处理对多孔钛生物活性和骨诱导的影响

2019-02-17 不详 网络

本研究旨在阐明用酸碱组合处理的多孔钛表面的生物活性和骨再生,并确定最佳的碱反应时间。制备10组多孔Ti,每组至少3个经历不同的酸碱处理时间。通过扫描电子显微镜(SEM),能量色散X射线光谱(EDS),二辛可宁酸方法(BCA),光学接触角测量和拉曼光谱测定表征表面。使用万能试验机进行压缩试验。通过使用模拟体液(SBF)测试,细胞增殖测试,纽蛋白,ALP和OCN表达以及细胞矿化的一系列生物测试来评估生

本研究旨在阐明用酸碱组合处理的多孔钛表面的生物活性和骨再生,并确定最佳的碱反应时间。

制备10组多孔Ti,每组至少3个经历不同的酸碱处理时间。通过扫描电子显微镜(SEM),能量色散X射线光谱(EDS),二辛可宁酸方法(BCA),光学接触角测量和拉曼光谱测定表征表面。使用万能试验机进行压缩试验。通过使用模拟体液(SBF)测试,细胞增殖测试,纽蛋白,ALP和OCN表达以及细胞矿化的一系列生物测试来评估生物活性和骨诱导。

结果显示,酸碱处理在样品表面上形成微米级和纳米级结构。碱处理12h达到最大的纳米级表面浮雕和最大的蛋白质吸收。经处理的多孔表面涂覆有NaHTiO 3层。酸-碱蚀刻不会损害多孔Ti样品的弹性模量和抗压强度。除羟基磷灰石外,在SBF中处理过的多孔样品上还形成钙钛矿相。未处理的致密Ti显示出更多的细胞粘附和增殖(P <0.05),而骨诱导和矿化在处理的多孔样品上更明显(P <0.05)。

总之,该研究结果表明,酸碱处理是在多孔Ti表面产生纳米级形貌的有效手段,有利于生物活性和骨再生。15min酸和12h碱蚀刻是最佳组合。骨诱导效力可归因于表面物理化学和羟基磷灰石和钙钛矿层的形成,而不是直接的细胞粘附和增殖。
