Abstract

A mathematical model is implemented to study the performance of an insulator-based dielectrophoretic device. The geometry of the device was captured in a computational model that solves Laplace equation within an array of cylindrical insulating structures. From the mathematical model it was possible to predict the location and magnitude of the zones of dielectrophoretic trapping of microparticles. Simulation and experimental results of trapping zones are compared for different operating conditions.

摘要

实现了一个数学模型来研究基于绝缘体的介电泳装置的性能。该装置的几何形状在一个计算模型中得以呈现，该模型求解圆柱形绝缘结构阵列中的拉普拉斯方程。通过数学模型，可以预测微粒介电泳捕获区域的位置和大小。针对不同的操作条件，对捕获区域的模拟结果和实验结果进行了比较。
