Abstract

Chitin and chitosan nanofibers (ChNF and CtsNF) are promising biomaterials due to their biocompatibility, biodegradability, and non-toxicity. This study investigates the cell adhesion properties and inflammatory responses of CtsNF, ChNF, and their mixtures when patterned on cellophane films using inkjet printing technology, keeping in mind their potential applications as cell culture scaffolds. The viscosities of 0.1 wt% aqueous dispersions of CtsNF, ChNF, and their mixtures were confirmed to be suitable for inkjet printing. Microstructures with varying thicknesses were fabricated by adjusting the printing parameters. Mouse fibroblast cells (L929) and mouse macrophages (RAW264.7) were used to evaluate cell adhesion and inflammatory responses. The results demonstrated that CtsNF microstructures exhibited excellent cell adhesion even for those as thin as ~140 nm and low inflammatory potential. This finding provides valuable insights into the development of advanced biomaterials for medical applications and could be instrumental in optimizing dosage settings for wound healing treatments as well.

评估喷墨打印图案化甲壳素和壳聚糖纳米纤维的细胞粘附性和炎症反应

甲壳素和壳聚糖纳米纤维（ChNF 和 CtsNF）具有生物相容性、生物可降解性和无毒性，是很有前途的生物材料。本研究考虑到 CtsNF、ChNF 及其混合物作为细胞培养支架的潜在应用，采用喷墨打印技术在玻璃纸薄膜上图案化后，研究了它们的细胞粘附特性和炎症反应。经证实，0.1 wt% 的 CtsNF、ChNF 及其混合物水分散体的粘度适合喷墨打印。通过调整打印参数，制造出了不同厚度的微结构。小鼠成纤维细胞（L929）和小鼠巨噬细胞（RAW264.7）被用来评估细胞粘附性和炎症反应。结果表明，CtsNF 微结构即使薄至 ~140 nm，也能表现出极佳的细胞粘附性和较低的炎症潜能。这一发现为开发先进的医用生物材料提供了宝贵的见解，同时也有助于优化伤口愈合治疗的剂量设置。
