摘要
液相生物离子操控技术已经成为生物样品分析领域的重要工具,通过成本低且易操作的简单装置可以在分析检测前对生物样品进行快速的预处理。生物离子在不同电场环境下,根据其受到的电泳力或介电泳力被操控。本篇综述了除常规毛细管电泳技术外,液相环境中的带电及中性生物粒子在均匀电场及非均匀电场下的操控技术。
Liquid phase biological ion manipulation technology had become an important tool in the field of biological sample analysis.The biological samples can be pretreated quickly before analysis and detection by a simple device with low cost and easy operation.Biological ions are manipulated according to their electrophoretic force or dielectrophoretic force under different electric field environments.In this paper,in addition to conventional capillary electrophoresis techniques,the control techniques of charged and neutral biological particles in liquid phase environment under uniform and non-uniform electric fields are reviewed.
