纳米多孔颗粒对于功能性纳米和微米系统的组装特别有趣，因为它们提供了各种客体分子的分级超分子组织。在这项工作中，通过将全息光镊（HOT）与聚合物刷功能化颗粒相结合来组装由纳米多孔沸石-L晶体组成的任意纳米结构，以克服沸石-L晶体的一维和受限自组装的限制。易于制备和官能化的聚合物壳允许受控的、即时的和高效的颗粒-颗粒和颗粒-表面粘附，而不需要外部触发。与早期研究相反，这些组件在从HOT系统中释放后保持永久稳定。这种新的策略可用于制造运动单元或局部接地的1D，2D和3D微结构，其可进一步用作微流体和纳米光子应用中的微工具。
Nanoporous particles are particularly interesting for the assembly of functional nano‐ and microsystems because they provide hierarchical supramolecular organization of a large variety of guest molecules. In this work, arbitrary nanoarchitectures consisting of nanoporous zeolite‐L crystals are assembled by combining holographic optical tweezers (HOT) with polymer brush functionalized particles to overcome the limitations of 1D and restricted self‐assembly of zeolite‐L crystals. Readily prepared and functionalized polymer shells allow for controlled, instant, and highly efficient particle–particle and particle–surface adhesion without the need for an external trigger. In contrast to earlier studies, these assemblies remain permanently stable after release out of the HOT system. This novel strategy can be used to fabricate either motile units or locally grounded 1D, 2D, and 3D microconstructions, which can be further utilized as microtools in microfluidic and nanophotonic applications.
