We introduce a general theory that explains the transient dynamic electrophoresis of a soft particle in an electrolyte solution when an oscillating electric field is suddenly applied. A simple approximate analytic expression is derived for the transient dynamic electrophoretic mobility of a soft particle that can be applied to practical situations. It is found that the mobility shows a damped oscillation, approaching its final value, similar to the behavior of a hard particle.

软粒子的瞬时动态电泳

我们引入了一个一般理论，解释了突然施加振荡电场时电解质溶液中软颗粒的瞬态动态电泳。推导了软粒子瞬态动态电泳迁移率的简单近似解析表达式，可应用于实际情况。研究发现，迁移率表现出阻尼振荡，接近其最终值，类似于硬粒子的行为。
