Fibrous structures in augmentation for rotator cuff repair: an experimental comparison

Construction and application of textile-based tissue engineering scaffolds: a review

Tissue engineering (TE) provides a practicable method for tissue and organ repair or substitution. As the most important component of TE, a scaffold plays a critical role in providing a growing environment for cell proliferation and functional differentiation as well as good mechanical support. And the restorative effects are greatly dependent upon the nature of the scaffold including the composition, morphology, structure, and mechanical performance. Medical textiles have been widely employed in the clinic for a long time and are being extensively investigated as TE scaffolds. However, unfortunately, the advantages of textile technology cannot be fully exploited in tissue regeneration due to the ignoring of the diversity of fabric structures. Therefore, this review focuses on textile-based scaffolds, emphasizing the significance of the fabric design and the resultant characteristics of cell behavior and extracellular matrix reconstruction. The structure and mechanical behavior of the fabrics constructed by various textile techniques for different tissue repairs are summarized. Furthermore, the prospect of structural design in the TE scaffold preparation was anticipated, including profiled fibers and some unique and complex textile structures. Hopefully, the readers of this review would appreciate the importance of structural design of the scaffold and the usefulness of textile-based TE scaffolds in tissue regeneration.

The Effect of Plasma Electron Temperature on the Surface Properties of Super-Hydrophobic Cotton Fabrics

The existing coating systems used for the preparation of super-hydrophobic surfaces are facing new challenges because the use of organic solvents and long-carbon-chain organic fluorine monomers is banned. In this article, the authors have proven that by using inductively coupled plasma-enhanced chemical vapor deposition (PECVD) with argon (Ar), which is a completely dry process, lauryl methacrylate (LMA) can produce a stable super-hydrophobic coating effect. The effect of electron temperature on the super-hydrophobicity of cotton fabrics is investigated in terms of water repellency, chemical composition, and surface morphology. It is found that the improvement in the hydrophobicity of cotton fabric is attributed to the deposition of alkyl and ester groups, and the formation of a micro–nano-structure on the surface of the fabric after plasma treatment. The electron temperature plays an important role in achieving the super-hydrophobicity of cotton fabrics. The plasma-enhanced coating may offer a safe and dry super-hydrophobic technique with diverse applications.
