Technical aspects of measurement of cellular electromagnetic activity
Electromagnetic fields generated by living cells have been experimentally investigated in the past 3 decades; however, the results are often inconsistent. In this paper we discuss some technical aspects of such challenging experiments, a brief review of which is also included. Special attention is paid to the sensor with respect to the power available from a cell and the power needed to excite the macroscopic measurement devices. We drew the conclusion that the nanoelectronic approach should be used.
