摘要
近年来,基于磷脂双分子层或胶体粒子稳定的图案化液滴网络得到了广泛研究,并在分区反应和生物应用等方面引起了极大兴趣.然而,现有液滴网络的设计方案受限于复杂的制备过程和液滴尺寸.本研究利用CB[8]表面活性剂在水-油界面的组装与堵塞相变,报道了一种多响应、内部连通且可在宏观尺度制备的图案化液滴网络.其制备过程简单快速,仅需要手动挤压即可构筑具有复杂形状的液滴网络.在此基础上,利用液滴之间的连通性可实现内部物质的传输、混合及化学反应,在微反应器、生物检测等领域具有重要的应用前景.
Abstract
In recent years,there has been significant research interest in the study of pattern droplet networks stabilized by lipid interfacial bilayers or colloidal particles.These networks offer great potential for compartmentalized reactions and biological functions.However,current studies are limited by the complex preparation process and droplet size.In this study,by utilizing the assembly and jamming of cucurbit[8]uril surfactants at the oil-water interface,a new approach to prepare droplet networks was presented that were multi-responsive,reconfigurable,and internally connected over macroscopic distances.Remarkably,this method only required manual compression to construct complex patterns of droplet networks.The opening between the droplets allows for the exchange of matter,facilitating chemical reactions and material synthesis,highlighting the potential applications in the field such as microreactors and biological.
