Abstract

Dielectrophoresis (DEP) is the movement of a particle in a non-uniform electric field due to the interaction of the particle's dipole and spatial gradient of the electric field. DEP is a subtle solution to manipulate particles and cells at microscale due to its favorable scaling for the reduced size of the system. DEP has been utilized for many applications in microfluidic systems. In this review, a detailed analysis of the modeling of DEP-based manipulation of the particles is provided, and the recent applications regarding the particle manipulation in microfluidic systems (mainly the published works between 2007 and 2010) are presented.

摘要

介电泳(DEP)是由于颗粒的偶极子与电场的空间梯度相互作用,导致颗粒在非均匀电场中的运动。由于其有利于系统尺寸减小的比例,DEP 是一种在微尺度上操纵颗粒和细胞的微妙解决方案。DEP 已在微流控系统的许多应用中得到利用。在这篇综述中,对基于 DEP 的颗粒操纵的建模进行了详细分析,并介绍了微流控系统中颗粒操纵的最新应用(主要是 2007 年至 2010 年期间发表的作品)。
