Devices with castellated electrodes. (A) Schematic of an insulator and 2D electrode device to focus and separate particles by applying different frequencies and amplitudes of an AC power supply [70]. (B) 3D drawing and scanning electronic microscopy image of the device. Reproduced with permission from [70], © 2008 Elsevier. (C) Schematic of the combined interdigitated and castellated electrode device. It was used to quantitatively evaluate the particle and cell separation.
