Abstract
A reference potential adjusting apparatus is provided. The reference potential adjusting apparatus includes a reference potential measuring unit configured to measure a potential of a solution, a counter electrode disposed in the solution, and configured to change the potential of the solution through oxidation-reduction reactions with the solution, and a comparator configured to compare a measurement voltage provided by the reference voltage measuring unit to a reference voltage provided by a reference voltage supply unit, and to adjust reactions of the counter electrode with the solution according to the result of the comparison. The reference potential measuring unit includes a reference electrode, a common electrode disposed to be spaced apart from the reference electrode, and at least one nano structure contacting the reference electrode and the common electrode, and having electrical conductivity changing according to the potential of the solution.
