标题： Hybrid dielectrophoretic-optical trap for microparticles in aqueous suspension

摘要： 我们证明了一组微加工电极可以与商用光学镊子设备耦合，实现一种具有多种功能的混合电光陷阱，用于操控悬浮的微纳米粒子。 我们的设计使我们能够同时在电极排列的低电场区域生成的单个势阱中捕获数十个粒子，利用了负介电泳效应。 结合光学镊子，我们展示了该混合方案允许增强的操控能力，包括从光学镊子中受控地加载和积累到介电泳陷阱中、选择性和跟踪被捕获粒子的个体轨迹。 显示英文摘要

摘要： We demonstrate that a set of microfabricated electrodes can be coupled to a commercial optical tweezers device, implementing a hybrid electro-optical trap with multiple functionalities to manipulate micro/nanoparticles in suspension. Our design allows us to simultaneously trap tens of particles in a single potential well generated in the low electric field region of the electrode arrangement, taking advantage of negative dielectrophoresis. Together with the optical tweezers, we show that the hybrid scheme allows enhanced manipulation capabilities, including controlled loading and accumulation in the dielectrophoretic trap from the optical tweezers, selectivity, and tracking of the individual trajectories of trapped particles.
