cattle disease is presented. The detector is based on an ELISA method with electrochemical
detection. A non-structural protein, 3ABC, is used to selectively detect antibodies is used to
selectively detect anti-3ABC antibodies produced after infection. The biological test is
performed onto a screen printed electrodes. A dedicated small, portable potentiostat is
employed for the control of the sensors, as well as data acquisition, processing, and storage.
