ABSTRACT:
A system and method for non-invasively measuring the electrical potential radiated by a cell. To do this, a probe is positioned within ten microns distance from the cell for receiving the signal. Also, a reference potential is determined for the cell's environment. A sensor records the signal and compares the reference potential to the cell's signal to measure the electrical potential of the cell.
