We studied the self-assembly of inorganic nanocrystals (NCs) confined inside nanoliter droplets (plugs) into long-range ordered superlattices. We showed that a capillary microfluidic platform can be used for the optimization of growth conditions for NC superlattices and can provide insights into the kinetics of the NC assembly process. The utility of our approach was demonstrated by growing large (up to 200 μm) three-dimensional (3D) superlattices of various NCs, including Au, PbS, CdSe, and CoFe(2)O(4). We also showed that it is possible to grow 3D binary nanoparticle superlattices in the microfluidic plugs.
我们研究了受限在纳升级液滴（塞子）中的无机纳米晶体（NC）的自组装，形成长程有序的超晶格。我们表明，毛细管微流控平台可用于优化 NC 超晶格的生长条件，并深入了解 NC 组装过程的动力学。通过生长各种 NC 的大（高达 200 μm）三维（3D）超晶格，包括 Au、PbS、CdSe 和 CoFe（2）O（4），证明了我们方法的实用性。我们还表明，在微流控塞中生长 3D 二元纳米颗粒超晶格是可能的。
