Description
技术领域
本发明涉及医疗卫生技术领域,尤其涉及一种抗菌抗病毒的纳米银胶体溶液及其制备方法和应用。
背景技术
自从1898年俄国科学家伊万诺夫斯基(Ivanovski)发现烟草花叶病毒以来,400多种与人类疾病相关的病毒被发现,据统计,90%以上的人类呼吸道传染病是由病毒所引起,随着免疫学的发展,许多病毒性疾病如天花、麻疹和小儿麻痹等得到了有效控制,但还有许多抗原性不强且易于突变的病毒如流感病毒、SARS(severe acute respiratorysyndrome,重症急性呼吸综合征)冠状病毒、禽流感病毒和人类免疫缺陷病毒(HIV,HumanImmunodeficiency Virus)及新型冠状病毒等的感染难以控制,有时或正在以比较严重的态势流行,此外,还有许多因为细菌所导致的疾病,这些都对人类健康造成了严重威胁,因此,防治细菌和病毒感染依然是人类面临的重大而迫切的任务。
其中,呼吸道病毒如流感病毒、SARS冠状病毒、禽流感病毒和新型冠状病毒等病毒的感染之所以难以控制,其主要原因是这些病毒在黏膜表面感染、抗原性弱且容易发生抗原变异和耐药性突变,从而导致了病毒耐药和病毒疫苗免疫作用不佳的结果。因此,面对人类呼吸道病毒种类众多、黏膜表面感染、抗原性弱且容易发生抗原变异和耐药性突变的特点,积极寻找安全有效、适宜于黏膜表面应用的广谱非特异性的抗菌抗病毒解决方案将具有十分重要的意义。
纳米银是利用纳米技术将金属银纳米化,纳米化的金属银具有很强的杀菌能力,银纳米化后,粒径达到纳米(nm)级状态,具有更大的比表面积,其物质单位越小,越能够有效的接触细菌和病毒,因为纳米银比细菌和病毒都小很多,从而能有效的接触细菌和病毒,进而最大限度发挥杀灭细菌和病毒能力。现有技术中,纳米银已被制作成各种抗菌抗病毒产品例如纳米银胶体溶液,纳米银安全有效、无耐药性,对多种细菌、真菌及病毒具有多靶位的“攻击”效应,具备广谱抗细菌、抗真菌和抗病毒的效能,且适宜于黏膜表面应用。但是,现有技术中,纳米银胶体溶液并不能很好地克服纳米银不够稳定的缺陷,从而限制了纳米银在医药领域里广谱抗菌抗病毒的广泛应用。
因此,如何提出一种安全有效、无耐药性、广谱抗菌抗病毒、适宜于黏膜表面应用且足够稳定的纳米银胶体溶液是当前亟待解决的技术问题。
