Microfluidic device for impednace spectroscopy of PC-3 cells

These video clearly show that at 5 MHz, cells experience pDEP and gravitational forces and they are captured inside the micro-wells, while at 10 kHz, nDEP pushes the PC-3 cells outside the wells, against gravity. Strong nDEP forces overwhelming the gravitational force are crucial for unloading the device. The video shows the cells are captured by pDEP, they remained packed during DS measurements and finally using nDEP will unload the wells and cells are washed away.
