摘要

纳米纤维素(Nanocellulose, BNC)是一种由细菌产生的天然聚合物。它的结构只有葡萄糖单体，具有高持水能力、独特的纳米结构、高结晶度和高机械强度等多种性能。纯BNC或与不同组件的组合可用于广泛的应用。芦荟是一种药用植物，其成分中含有多糖，具有组织再生和修复的潜力。本研究的目的是评价芦荟提取物(BNC-Aloe)三组分制备的BNC膜中掺入芦荟对上皮细胞行为的影响。与对照相比，在bnc -芦荟膜上培养的人成纤维细胞和角化细胞具有更高的代谢活性和增殖能力。bnc -芦荟膜中胶原生物合成的定量明显增加。综上所述，bnc -芦荟膜被认为是一种新型的膜材料

Incorporation of Aloe vera extract in bacterial nanocellulose membranes

Florianópolis, SC, Brasil *piaialyapi@gmail.com Obstract Nanocellulose (BNC) is a natural polymer produced by bacteria. Its structure has only glucose monomer, it has various properties such as high water holding capacity, unique nanostructure, high crystallinity and high mechanical strength. Pure BNC or in combination with different components can be used for a wide range of applications. Aloe vera is a medicinal plant with polysaccharides in its composition that has a potential for tissue regeneration and repair. The aim of this study was to evaluate the effect of incorporating Aloe vera ( A. vera ) into BNC membranes produced with three fractions of A. vera extract (BNC-Aloe) on the behavior of epithelial cells. Human fibroblasts and keratinocytes were shown to have increased metabolic activity and proliferation when cultured on BNC-Aloe membranes compared to control. Quantification of collagen biosynthesis was significantly higher in BNC-Aloe membranes. In conclusion, BNC-Aloe membranes are suggested as a material for the
