    • A method of trapping a charged particle. The method includes providing a planar substrate having a conductive surface thereon, the conductive surface having at least one non-conductive region. The method also includes applying a solution to the conductive surface, the solution comprising at least one charged particle. The method further includes applying a voltage of a threshold level to the conductive surface. The method also includes, in response to the voltage, generating an electrostatic field in the solution adjacent to a boundary between the conductive surface and the non-conductive region. The method also includes setting the threshold level of voltage to result in a strength of the electrostatic field sufficient to prevent the particle from crossing the electrostatic field.
    • 捕获带电粒子的方法。 该方法包括提供其上具有导电表面的平面基板,该导电表面具有至少一个非导电区域。 该方法还包括将溶液施加到导电表面,该溶液包含至少一个带电粒子。 该方法还包括向导电表面施加阈值电平的电压。 该方法还包括响应于电压,在与导电表面和非导电区域之间的边界相邻的溶液中产生静电场。 该方法还包括设置电压的阈值电平以产生足以防止颗粒穿过静电场的静电场的强度。
