只需用盐 即可把普通外科口罩改造成病毒灭活装置

来自加拿大阿尔伯塔大学的Hyo-JickChoi和同事在普通外科口罩的纤维过滤层上添加一种特殊的氯化钠盐涂层,将其转化为一套通用且可重复使用的病毒灭活系统。

  
《科学报告》1月4日发表的一篇名为Universal and reusable virus deactivation system for respiratory protection的文章,为应对流行性呼吸疾病爆发提供了一种廉价而高效的防护装置。来自加拿大阿尔伯塔大学的Hyo-Jick Choi和同事在普通外科口罩的纤维过滤层上添加一种特殊的氯化钠盐涂层,将其转化为一套通用且可重复使用的病毒灭活系统。

雾化传播病原体是引起呼吸感染和疾病传播的一个重要原因。目前使用的防护措施缺乏有效的病毒灭活功能,因此会带来潜在的初次及二次感染与传播的风险。

Hyo-Jick Choi与同事通过在口罩滤芯上包裹一层氯化钠盐来达到病毒灭活的效果。这些覆盖在纤维表面的盐在接触病毒气溶胶时发生溶解,在干燥过程中再次结晶,从而杀死病原体。在密封测试中,盐覆盖滤芯在过滤效率上明显高于传统口罩过滤层。用经盐覆盖滤芯过滤过的病毒感染实验鼠,获得了100%的存活率。作者还论证了该项技术对任何亚型的流感病毒都具有高效的灭活功能,且不会受极端环境储存条件的影响。

这项结果可应用于广谱空气传播病原体防疫装置的开发,为区域性和大面积流行性呼吸道疾病的爆发做准备。
