为了从水中去除病毒，使用自组装液晶作为一种合成具有规则孔径（小于1nm）和控制孔结构的膜的新方法。将纳米结构的双连续立方液晶（LC）薄膜光聚合在聚砜支撑层上。研究发现，这些膜对Q β噬菌体（直径约20 nm）的排斥力达到99.9999%。膜的预加压似乎增强了它们的病毒排斥特性。这是纳米结构LC膜用于病毒排斥的第一个例子，它们显示出巨大的潜力。
To remove viruses from water, the use of self-assembling liquid crystals is presented as a novel method for the synthesis of membranes with a regular pore size (below 1 nm) and controlled pore structures. Nanostructured bicontinuous cubic liquid-crystalline (LC) thin films are photopolymerized onto a polysulfone support layer. It is found that these membranes reject the virus, Q beta bacteriophage (approximate to 20 nm diameter) by >99.9999%. Prepressurization of the membrane appears to enhance their virus rejection properties. This is the first example of nanostructured LC membranes that are used for virus rejection, for which they show great potential.
