J Nanosci Nanotechnol:等离子体处理纳米管的抗菌及成骨性能如何?

2018-05-09 MedSci MedSci原创

本研究旨在评估热处理及等离子体处理TiO2纳米管对牙龈卟啉单胞菌的抗菌活性及成骨细胞活力的影响。将样品分成四组:Ti(抛光钛),Nano(TiO2纳米管),NH300(300℃下在TiO2纳米管上进行热处理)和NH400(400℃下在TiO2纳米管上进行热处理)组。根据等离子体处理在四组中评估抗菌活性和成骨细胞活力。结晶紫测定评估牙龈卟啉单胞菌的表面粘附。XTT测定检查成骨细胞的活力。 结果显示,

本研究旨在评估热处理及等离子体处理TiO2纳米管对牙龈卟啉单胞菌的抗菌活性及成骨细胞活力的影响。

将样品分成四组:Ti(抛光钛),Nano(TiO2纳米管),NH300(300℃下在TiO2纳米管上进行热处理)和NH400(400℃下在TiO2纳米管上进行热处理)组。根据等离子体处理在四组中评估抗菌活性和成骨细胞活力。结晶紫测定评估牙龈卟啉单胞菌的表面粘附。XTT测定检查成骨细胞的活力。

结果显示,Ti组、Nano组和NH 300组血浆等离子体处理后牙龈卟啉单胞菌的粘附率明显降低(P <0.05)。与钛组相比,等离子体处理前NH 400组的成骨细胞活力增加(P <0.05)。

综上所述,该研究结果表明,等离子体处理降低了牙龈卟啉单胞菌的粘附,但对成骨细胞的活化没有影响。

Nanotechnology:ZnO纳米颗粒包埋入TiO2纳米管的抗菌活性和抑炎作用

具有纳米级结构表面的钛(Ti)表现出优异的生物相容性和骨整合。但是,手术植入可能导致细菌感染和炎症反应,从而导致植入失败。在这项工作中,研究人员通过电沉积将不规则和纳米棒形状的ZnO纳米颗粒掺入到内径约50nm的TiO2纳米管(TNT)中。使用金黄色葡萄球菌评估纳入TiO2纳米管(TNTs/ZnO)中的ZnO的抗菌性能。结果显示,与TNT相比,锌离子可从纳米粒子中释放,抗菌效果提高达99.3%。在
