本专利技术属于材料领域,具体涉及一种二苯甲酮类离子液、抗菌材料及其制备方法。
技术介绍
细菌、真菌和病毒等病原微生物能引发机体组织发生病变,严重威胁着人类健康。2011年,美国发生72.2万例院内感染,导致近7.5万病人死亡。每年增加医疗费用45~110亿美元。医疗器械在介(植)入体内后,在其表面滋生细菌是引发体内感染的最主要原因,给病患带来巨大的痛苦,甚至会导致残疾,危及生命安全。细菌在生物医用材料表面粘附是引起感染的第一步,细菌先要粘附于物质表面,然后通过信号分子进行相互间的信息交流,引来同类细菌聚集,从而形成完整的生物膜结构(PavithraD.,etal..Biofilmformation,bacterialadhesionandhostresponseonpolymericimplants—issuesandprevention.BiomedicalMaterials2008;3:034003)。生物膜一旦形成,膜内细菌抵抗抗生素等杀菌药物及对抗机体免疫系统清除的能力将大大加强,从而引起细菌持续性感染。因此,针 ...
