电泳是电介质中带电粒子在电场作用下以不同的速度向电荷相反方向迁移的现象。1937年瑞典科学家A．TISSliSS首先把它作为一种分离技术应用在生物和生物化学领域中，并取得了突破性进展。但传统电泳的分离效率受焦耳热的限制，只能在低电场强度下进行电泳操作，以致于使分析时间 Electrophoresis is the phenomenon that charged particles in a dielectric migrate in the opposite direction at different speeds under the action of an electric field. 1937 Swedish Scientist TISSliSS first used it as a separation technology in the field of biology and biochemistry, and made a breakthrough. However, the separation efficiency of traditional electrophoresis is limited by Joule heat and the electrophoresis operation can only be performed under low electric field strength, so that the analysis time
