粒子操纵技术在药物筛选、疾病检测和治疗等方面具有重要意义。本文报道了基于空间电场的多畴定向粒子链及其光学应用。根据粒子介电行为的差异，利用介电泳力和电渗旋转成功实现了凝胶中多畴取向粒子链的制备。这为制备多结构、多层、多功能的智能响应材料提供了新的思路。此外，还讨论了影响凝胶中粒子排列高度的因素，为制备双层粒子链奠定了基础。粒子组装作为结构层次化的一个实例，在光电子器件和软机器人等领域有着广阔的应用前景。
The manipulation technology of particles is significant in drug screening, disease detection and treatment, etc. Here, we reported the multidomain oriented particle chains based on a spatial electric field and their optical application. According to the differences in the dielectric behavior of particles, the preparation of multidomain oriented particle chains in the gel was successfully realized by using the dielectrophoretic force and electroosmotic rotation. This provides a new idea for manufacturing multistructure, multilayer, and multifunctional intelligent response materials. In addition, the factors affecting the alignment height of the particles in the gel were discussed, which was the basis for the preparation of bilayer particle chains. As an example of structural hierarchy, particle assembly has broad application prospects in optoelectronic devices and soft robots.
