1. A method for separating target material from other material in a fluid sample, the method comprising the steps of:

  • a) forcing the fluid sample to flow through a separation device, the separation device comprising a substrate and a plurality of structures on the substrate, each of the structures being coated with an electrical insulator film;

    b) applying a voltage to the structures while the sample flows through the device, thereby attracting the target material to the insulator film while the other material passes through the device; and

    c) eluting the target material from the device.
