  Adenosine triphosphate (ATP) is a highly energetic molecule used as a
coenzyme in the transfer of chemical energy required for the continuation of
cellular metabolism. In addition, extracellular ATP has an important role in
cell-to-cell communication in immune, nervous and vascular systems. ATP is
detected mainly using commercially available luciferin-luciferase kits and this
method does not allow local measurement. In this study, first carbon-fiber
microelectrodes capable of local detection were fabricated and then, the
surface of these electrodes were modified with enzymes for detection of
non-electroactive ATP molecules.
