Therefore, we put this solution aside and in order to solve the problem electrode C2 is chosen as the point of current injection and the
base electrode is chosen to be C8.
Each CNT row must have a different
base electrode so that a different potential can be applied to it.
The
base electrode was cleaned by giving a dip in 50% nitric acid solution and thorough washing with distilled water ensuring complete removal of any previous deposit on the base, before starting every new electrodeposion.
Attraction of the functionalized magnetic nanoparticles to the probe surface with an external magnet activates the electrical contact between the immobilized proteins and the
base electrode, and the sensor's circuit is switched on.
The activity of lead dioxide is increased with increasing the concentration of cerium ions in the PbO2 deposits but due to enhanced passivity of the
base electrode the activity of the deposit increases.
