摘要

我们证明了一组微加工电极可以耦合到商业光学镊子设备上，实现了一个具有多种功能的混合电光平台，用于操纵悬浮液中的微/纳米颗粒。我们表明，混合方案可以增强操作能力，包括混合动力学，控制光镊在介电阱中的积累，选择性和捕获粒子的单个轨迹的视频跟踪。这为统计物理和随机热力学与多粒子系统的新研究创造了机会，以前仅限于单个粒子的研究。

A hybrid dielectrophoretic trap–optical tweezers platform for manipulating microparticles in aqueous suspension†

We demonstrate that a set of microfabricated electrodes can be coupled to a commercial optical tweezers device, implementing a hybrid electro-optical platform with multiple functionalities for the manipulation of micro-/nanoparticles in suspension. We show that the hybrid scheme allows enhanced manipulation capabilities, including hybrid dynamics, controlled accumulation in the dielectrophoretic trap from the optical tweezers, selectivity, and video tracking of the individual trajectories of trapped particles. This creates opportunities for novel studies in statistical physics and stochastic thermodynamics with multi-particle systems, previously limited to investigations with individual particles.

期刊介绍： Lab on a Chip is the premiere journal that publishes cutting-edge research in the field of miniaturization. By their very nature, microfluidic/nanofluidic/miniaturized systems are at the intersection of disciplines, spanning fundamental research to high-end application, which is reflected by the broad readership of the journal. Lab on a Chip publishes two types of papers on original research: full-length research papers and communications. Papers should demonstrate innovations, which can come from technical advancements or applications addressing pressing needs in globally important areas. The journal also publishes Comments, Reviews, and Perspectives.
