The results obtained with the capacitive biosensor show that the hybridization of Target_Parvum on the electrode surface produces a signal that is proportional to the concentration of the
DNA (Fig. 5) even though the dispersion of the data obtained in these initial measurements is quite large. When the HCR was performed on the electrode surface, the resulting capacitive
signals increased, while still being proportional to the Target concentration. Although the standard deviation of the HCR signal is bigger than the one of the Target, the measurements on the capacitive biosensor confirm that the HCR allows the detection of a smaller concentration of target than the measurements of the target alone. Even in this non-optimized case, the limit of detection after amplification lies between 0.1 and 0.5 mM, while it is close to 1 mM for the target alone.
