新奇高紧张的 TiO2 nanotubes 数组膜经由高度纯的钛陪衬的电气化学的阳极化被制作,无限制的 TiO2 nanotubes 数组膜被在 nanotubes 的底部蚀刻的 HF 气体获得。猪管状的上皮的房间(LLC-PK1 ) 和脉管的 endothelial 房间(ECV304 ) 与生理的功能通过一个混合培植方法和 TiO2 nanotubes biomembrane 材料在无限制的 TiO2 nanotubes 表面上被栽培成功地被生产。玻璃幻灯片,纯钛,没有房间的 TiO2 nanotubes 和有文化房间的 TiO2 nanotubes 的 Hemocompatibility 被血浆石灰化时间方法和钠的重吸收调查,钾被设计习俗的设备测量。结果证明有文化房间的 TiO2 nanotubes 数组膜的 hemocompatibility 比控制组优异,并且 biomembrane 有一个优秀重吸收函数。这证明 TiO2 nanotubes 数组膜有优秀生理的功能并且是为生物分离的理想的候选人材料。
A novel high-intensity TiO2 nanotubes array membrane was fabricated via electrochemical anodization of highly pure titanium foil and an open-ended TiO2 nanotubes array membrane was obtained by HF gas etching at the bottom of the nanotubes. Pig tubular epithelial cells (LLC-PK1) and vascular endothelial cells (ECV304) were cultivated on the open-ended TiO2 nanotubes surface through a mixing implantation method and TiO2 nanotubes biomembrane materials with physiological function were successfully produced. Hemocompatibility of glass slides, pure titanium, TiO2 nanotubes without cells and TiO2 nanotubes with culture cells were investigated by the plasma recalcification time method and reabsorption of sodium and potassium were measured by custom-designed devices. The results show that the hemocompatibility of the TiO2 nanotubes array membrane with culture cells was superior to the control group, and the biomembrane has an excellent reabsorption function. This demonstrates that a TiO2 nanotubes array membrane has excellent physiological function and is an ideal candidate material for biological dialysis.
