Description

三叶青多糖修饰的硫掺杂氮化碳纳米片材料的制备方法
技术领域
本发明涉及氮化碳材料抗菌性能的应用技术,具体是一种三叶青多糖修饰的硫掺杂氮化碳超薄纳米片抗菌材料的制备方法。
背景技术
三叶青(Tetrastigma hemsleyanum Diels & Gilg)又名三叶崖爬藤,又名金线吊葫芦、蛇附子,生长于阴湿山坡、山谷等地带,主要分布在我国浙江、福建、广西、云南等地。三叶青全草均可入药,是我国著名的中草药之一,具有显著的药用价值,如治疗病毒性脑膜炎、支气管炎、小儿高热惊厥、预防以及治疗癌症等。
氮化碳作为一种光催化活性物质,具有独特的二维结构。石墨相氮化碳具有结合能低,化学稳定性好,电子结构可调,生物相容性好的优点。为了将石墨相氮化碳应用在药物研发领域上,近年对氮化碳的改性取得了显著的成果,主要可以采用掺杂其他元素,微观结构调整等方法。由于氮化碳独特的片层结构,目前已经被报道其对菌体的切割作用,从而实现优越的抗菌效果。通过对氮化碳材料的修饰改进,从而增加其单分散性实现高效抑菌效果。
本发明研究了复合材料对革兰氏阴性菌,大肠杆菌的抑制效果,旨在提供一种基于三叶青多糖修饰的硫掺杂氮化碳纳米片在制备抗炎抗菌药物中的应用。
发明内容
本发明的目的在于提供三叶青多糖修饰的硫掺杂氮化碳纳米片材料的制备方法,以解决上述背景技术中提出的问题。
为实现上述目的,本发明提供如下技术方案:
三叶青多糖修饰的硫掺杂氮化碳纳米片材料的制备方法,包括以下步骤:
步骤100,提取三叶青粗多糖;
步骤200,制备三叶青多糖粗蛋白;
步骤300,制备超薄硫掺杂氮化碳纳米片:称取二氰二氨与2,5-噻吩二羧酸放在干燥的烧杯中,再加入超纯水,在60°C蒸干将蒸干的粉末研磨均匀;
步骤400,制备三叶青多糖修饰超薄硫掺杂氮化碳纳米片复合物:在有氮气的保护下煅烧得到红色粉末均匀物质;配制200 ppm浓度的三叶青多糖水溶液,加入红色粉末均匀物质,混匀;超声30 min,直至无明显沉淀产生,溶液即为复合物悬浊液。
作为本发明进一步的方案:所述步骤100提取三叶青粗多糖的方法为:称取干燥三叶青粉末,用无水乙醇提取后弃去上清液;用超纯水提取抽滤得到滤液,水浴浓缩至原体积的1/4;加入4倍体积的95%乙醇,沉淀静止过夜;离心收集沉淀,经冷冻干燥后得粗多糖。
作为本发明进一步的方案:所述步骤100中,无水乙醇提取和超纯水提取的温度为45-55℃。
作为本发明进一步的方案:所述步骤200制备三叶青多糖粗蛋白的方法为:称取三叶青粗多糖,超声溶解完全后,按比例加入氯仿和正丁醇,充分搅拌离心,弃去有机层和蛋白层,重复三次,直至无蛋白质白色沉淀产生为止;使用超纯水透析48h,冷冻干燥获得三叶青精多糖。
作为本发明进一步的方案:所述步骤200中,所述三叶青粗多糖:氯仿:正丁醇的添加体积比为:三叶青粗多糖:氯仿:正丁醇=8:4:1。
作为本发明进一步的方案:所述步骤300中,二氰二氨与2,5-噻吩二羧酸的重量比为300:1。
作为本发明进一步的方案:所述步骤400中,氮气保护下煅烧参数为:在550°C温度下煅烧4小时,升温速率为2.3°C。
与现有技术相比,本发明的有益效果是:本发明涉及的三叶青多糖,可以在短暂的药物作用时间上显著的杀死细菌,并且长时间维持细菌无法增殖,具有很好的抗菌抑菌作用,而单一的SCNNSs能够在给药后3小时发挥抗菌效果,但是由于其单分散性较差,无法实现较好的抗菌性能。在库伦作用力作用下三叶青多糖能够和SCNNSs相结合形成复合材料TPS-SCNNSs,从而提高SCNNSs的单分散性,能够实现快速长时间的抑菌效果。
