摘要： 光伏微流体操控技术利用非均匀光伏电荷场对流体目标的静电作用来实现非接触操控。近年来,基于铌酸锂的光伏微流体操控技术逐渐引起人们的关注,并有望成为铌酸锂基生物光子芯片微流体操控功能的关键支撑技术。与传统的全电微流体操控和光镊操控相比,铌酸锂基光伏微流体操控不需要外部电源供电,不需要复杂电极的制备,所需操控光强低,作用范围广,因此可以最大程度地避免外界对内部生物环境的污染和干扰。本文介绍了铌酸锂基光伏微流体操控的理论基础,系统阐述了铌酸锂基光伏微流体操控的近期研究进展。

Abstract: Photovoltaic microfluidic manipulation utilizes electrostatic interaction of a non-uniform photovoltaic electrostatic field on microfluidic targets to achieve non-contact manipulation. Recently, photovoltaic microfluidic manipulation based on lithium niobate (LN) has been paid a lot of attention, and is considered as a key technology for LN-based biophotonic chips. Compared with traditional electrical and optical manipulation, photovoltaic microfluidic manipulation, using only low-power laser beams but being valid for mass of targets in a wide range, doesn’t require external power sources and fabrication of complex electrode structures, and therefore can avoid external pollution and interference to internal biological environment. In this paper, theoretical basis of photovoltaic microfluidic manipulation based on LN is introduced and the recent achievements in this field is reviewed.

Key words: lithium niobate, photovoltaic effect, microfluid, photovoltaic manipulation, dielectric droplet, water droplet
