Abstract :
A ZnO nanorod probe was employed to determine the resting membrane potential of a human fat cell. The distribution of protons associated with the cell versus the extracellular distribution is proportional to changes in membrane potential. The membrane potential determines the concentration gradient of the protons with dominant permeability according to the Nernst equation. A ZnO nanorod probe was successfully used to find the resting membrane potential for a human fat cell: 34 ± 2.6 mV.
