钛及其合金目前被认为是一种成功的生物相容性材料，因为钛制成的植入物在结构和功能上都很容易与生物系统连接。就生物系统而言，医用植入物的抗菌活性值得关注，以防止植入部位的炎症。在这项研究中，射频冷等离子体被用作潜在的技术来防止或降低细菌对Ti样品的活性。为了寻找对大肠杆菌32的最佳抑菌工艺条件，研究了几种血浆参数。本研究的主要结果表明，钛样品在几个实验装置中表现出较高的抗菌活性。此外，治疗后16天检测到的抗菌活性与治疗前相同，表明血浆表面修饰的有效性。最后，尝试将抗菌效果与等离子体处理后的钛表面能和等离子体参数联系起来。
Titanium and its alloys are currently considered as successful biocompatible materials because titanium made implants become easily, structurally and functionally, connected to biological systems. As far as biological systems is concerned, antibacterial activity for medical implants are worth of interest to prevent inflammation at implant site. In this study RF cold plasma is employed as potential technology to prevent or reduce bacterial activity on Ti samples. Several plasma parameters are investigated for finding the best antibacterial process conditions against Escherichia coli 32. Main results of this investigation show that high antibacterial activity is exhibited by Ti samples in several experimental set-ups. In addition, the antibacterial activity detected at same level of previous, 16 days after the treatment suggests the effectiveness of the plasma surface modification. Finally, an attempt is made to correlate antibacterial effect with plasma treated titanium surface energy and plasma parameters.
