本研究以N,N-二甲基乙醇胺,丙烷磺内酯和均三嗪为原料,合成一种带有反应性基团的两性离子磺酸甜菜碱中间体,然后以三嗪为桥基接枝到壳聚糖上得到三嗪类磺基甜菜碱改性壳聚糖(CS-SNCC),通过溶液流延法制备了可生物降解CS-SNCC抗菌膜。采用傅里叶变换红外(FTIR)、紫外-可见(UV-Vis)、能量色散X射线(EDX)和X射线分析光电子能谱(XPS)光谱对合成的CS-SNCC结构进行表征分析。对CS-SNCC膜的溶胀性能、热稳定性、生物降解性、细胞相容性和抗菌性能进行了全面系统的研究,并与壳聚糖膜进行了比较。酶生物降解性能测试结果表明,CS-SNCC薄膜在溶菌酶的作用下21天内可降解45.54%。CS-SNCC膜可以有效抵抗细菌黏附,防止细菌生物膜的形成,并表现出较高的抗菌活性,与CS膜相比,CS-SNCC膜表面黏附的细菌数目分别减少了86.89%和94.19%,并可在60 min内杀死93.43%的大肠杆菌和91.00%的金黄色葡萄球菌。此外,细胞毒性结果表明CS-SNCC膜显示出良好的细胞活性和细胞相容性。因此,制备的可生物降解、细胞相容、抗菌和生物膜控制的CS-SNCC膜具有极大的生物医学应用潜力。

Transplantation of probiotics to the intestine can positively regulate the gut microbiota, thereby promoting the immune system and treating various diseases. However, the harsh gastrointestinal environment and short retention time in the gastrointestinal tract significantly limit the bioavailability and intestinal colonization of probiotics. Herein, we present a double-layer polysaccharide hydrogel (DPH) in the form of a double-layer structure composed of a carboxymethyl cellulose (CMCL) supramolecular inner layer and a dialdehyde alginate (DAA) cross-linked carboxymethyl chitosan (CMCS) outer layer. This double-layer structure allows DPH to encapsulate and deliver probiotics in a targeted manner within the body. In the stomach, the cage structure of the DPH is closed, and the outer layer absorbs surrounding liquids to form a barrier to protect the probiotics from gastric fluids. In the intestine, the cage structure opens and disintegrates, releasing the probiotics. Thus, DPH endows probiotics with excellent intestine-targeted delivery, improved oral bioavailability, enhanced gastrointestinal tract tolerance, and robust mucoadhesion capacity. The encapsulated probiotics exhibit almost unchanged bioactivity in the gastrointestinal tract before release, as well as improved oral delivery. In particular, probiotics encapsulated by DPH exhibit 100.1 times higher bioavailability and 10.6 times higher mucoadhesion than free probiotics in an animal model 48 h post-treatment. In addition, with a remarkable ability to survive and be retained in the intestine, probiotics encapsulated by DPH show excellent in vitro and in vivo competition with pathogens. Notably, DAA-mediated dynamic crosslinking not only maintains the overall integrity of the hydrogels but also controls the release timing of the probiotics. Thus, it is expected that encapsulated substances (probiotics, proteins, etc.) can be delivered to specific sites of the intestinal tract by means of DPH, by controlling the dynamic covalent crosslinking.
