光伏光电子镊子（PVOT）已被证明是用于微/纳米物体的操纵和大规模组装的有效工具。该技术依赖于由某些铁电材料在照射时由于体光伏效应而产生的强电场（通常为LiNbO 3：Fe）。尽管PVOT的快速发展以及高质量的1D和2D粒子图案化的实现，但针对由多种类型的粒子组成的组合结构的制造的研究工作一直很少。在此，我们制定了三种不同方法的工作原则，以应对这一悬而未决的挑战。为此，已经适当地利用了分别作用于中性和带电粒子的介电泳和/或电泳。已经获得了不同尺寸的金属和介电纳米颗粒组合的简单混合结构。这些结果为未来通过PVOT制造更复杂的组合结构奠定了基础，其中微米/纳米颗粒是小型化功能器件的基本构建模块。
Photovoltaic optoelectronic tweezers (PVOTs) have been proven to be an efficient tool for the manipulation and massive assembly of micro/nano-objects. The technique relies on strong electric fields produced by certain ferroelectric materials upon illumination due to the bulk photovoltaic effect (customarily LiNbO3:Fe). Despite the rapid development of PVOTs and the achievement of high-quality 1D and 2D particle patterning, research efforts aimed at the fabrication of combinatorial structures made up of multiple types of particles have been scarce. Here, we have established the working principles of three different methods to tackle this pending challenge. To that end, dielectrophoresis and/or electrophoresis acting on neutral and charged particles, respectively, have been suitably exploited. Simple mixed structures combining metallic and dielectric nanoparticles of different sizes have been obtained. The results lay the groundwork for future fabrication of more complex combinatorial structures by PVOT, where micro/nanoparticles are the basic building blocks of miniaturized functional devices.
