摘要
富血小板纤维蛋白(PRF)的质量取决于与血液接触的表面特性。钛的血小板活化性能优越,超过了二氧化硅,因此钛富血小板纤维蛋白(T-PRF)的降解时间较长,是一种受青睐的自体骨移植材料。本研究开创了一种新方法,旨在使用涂有纳米钛的玻璃管实现增强的纤维蛋白结构,这标志着该表面首次出现在我们的富血小板纤维蛋白生产中。我们采用高真空下的快速热离子真空电弧(TVA)工艺,对玻璃管进行了全面分析。我们对纳米钛涂层玻璃管进行了全面分析,包括 X 射线衍射 (XRD)、原子力显微镜 (AFM)、扫描电子显微镜 (SEM) 和能量色散 X 射线光谱 (EDS)。共配制了三种 PRF:二氧化硅激活的富含白细胞和血小板的纤维蛋白(L-PRF,对照组)、机加工表面钛管(T-PRF)和纳米钛涂层管(nanoT-PRF)。分析结果显示,纳米钛管比钛管的纤维蛋白区域更密集,而 L-PRF 的纤维蛋白区域密度最低。细胞分布在 nanoT-PRF 组和 T-PRF 组之间,而 L-PRF 组细胞嵌入纤维蛋白边界。NanoT-PRF 表现出最致密的自体纤维蛋白结构,表明其在体内的吸收时间较长。此外,我们还探索了一次性生产纳米T-PRF管的潜在实用性,为临床应用带来了希望。这项研究标志着创新生物材料设计取得了重大进展,为再生医学的发展做出了贡献。
Nano-titanium coating on glass surface to improve platelet-rich fibrin (PRF) quality
The quality of platelet-rich fibrin (PRF) is contingent on the surface characteristics interfacing with blood. Titanium’s superior platelet activation, surpassing silica, has made Titanium-platelet-rich fibrin (T-PRF) a favored autogenous bone graft material due to its extended degradation time. Pioneering a novel approach, this study aims to achieve an enhanced fibrin structure using glass tubes coated with nano-titanium, marking the surface’s debut in our PRF production endeavors. Employing a rapid thermionic vacuum arc (TVA) process under high vacuum, we conducted comprehensive analyses of the tubes. Comprehensive analyses, including X-ray diffraction (XRD), atomic force microscopy (AFM), scanning electron microscopy (SEM), and energy dispersive X-ray spectroscopy (EDS), were conducted on the nano-titanium-coated glass tubes. Three PRF types were formulated: silica-activated leukocyte- and platelet-rich fibrin (L-PRF, control group), machined-surface titanium tubes (T-PRF), and nano-titanium-coated tubes (nanoT-PRF). Analyses unveiled denser fibrin areas in nanoT-PRF than T-PRF, with the least dense areas in L-PRF. Cell distribution paralled between nanoT-PRF and T-PRF groups, while L-PRF cells were embedded in the fibrin border. NanoT-PRF exhibited the densest autogenous fibrin structure, suggesting prolonged in vivo resorption. Additionally, we explore the potential practicality of single-use production for nanoT-PRF tubes, introducing a promising clinical advancement. This study marks a significant stride in innovative biomaterial design, contributing to the progress of regenerative medicine.
