Abstract

In this paper, we report the development of a dielectrophoresis cell separation chip and present the preliminary results. Both dielectrophoresis force and size filtering microstructure are incorporated in our microchip for the function of cell separation. By applying individual input voltage with different frequency on the different rows of the micro-tips, different particles could be separated in our device based on their size and electric property. An additional micro-structure design filter is also adopted in this chip to function as a multi-size filter to enhance the separation efficiency. Analysis, simulation, and experimental demonstration are reported in this paper to verify the functions of our separation chip.
一种采用微结构滤波和多频介质电泳的细胞分离芯片
本文报道了一种介质电泳细胞分离芯片的研制,并给出了初步结果。我们的微芯片结合了介电泳力和尺寸过滤微结构来实现细胞分离功能。通过在不同排的微针尖上施加不同频率的单独输入电压,可以根据颗粒的大小和电学性质在我们的装置中分离不同的颗粒。该芯片还采用了额外的微结构设计过滤器,作为多尺寸过滤器,以提高分离效率。本文通过分析、仿真和实验演示来验证分离芯片的功能。
