Biomaterials:分层纳米纤维海绵具有改善的促进血液凝固和伤口愈合的能力

2019-04-27 不详 网络

有效的出血控制和伤口愈合非常重要,可以挽救生命。然而,具有结构缺陷的传统伤口敷料在控制出血和促进功能性组织的再生方面无效。在该研究中,通过将二维(2D)纳米纤维膜扩展到三维来获得三维(3D)层状纳米纤维海绵。这种海绵具有分层的纳米纤维结构,增加了海绵和血细胞之间的界面相互作用,加速了止血。通过微调结构,3D纳米纤维海绵获得了有利于伤口愈合的性质,例如良好的弹性,高渗透性和流体吸收率。3D纳米纤维海

有效的出血控制和伤口愈合非常重要,可以挽救生命。然而,具有结构缺陷的传统伤口敷料在控制出血和促进功能性组织的再生方面无效。在该研究中,通过将二维(2D)纳米纤维膜扩展到三维来获得三维(3D)层状纳米纤维海绵。这种海绵具有分层的纳米纤维结构,增加了海绵和血细胞之间的界面相互作用,加速了止血。

通过微调结构,3D纳米纤维海绵获得了有利于伤口愈合的性质,例如良好的弹性,高渗透性和流体吸收率。3D纳米纤维海绵具有高度可压缩性和弹性,可为深部伤口提供填塞,并创建良好的3D动态微环境以调节细胞行为。进一步的研究表明,层状纳米纤维结构可以在早期修复阶段促进功能性真皮的再生和分化的脂肪细胞的恢复。使用具有全厚度皮肤缺陷的模型小鼠的实验已经表明,层状纳米纤维结构可以有效地加速伤口愈合并减少瘢痕形成。

这种分层3D纳米纤维海绵设计易于生产。由于其优异的伤口愈合性能,这种多孔纳米纤维海绵作为伤口敷料具有很大的未来临床应用潜力。
