a DNA extracted from clinical sample and presence of DNA of HPV type 18 virus on gel electrophoresis; b the differential pulse voltammograms for the AQMS electrochemical reduction after hybridization with DNA extract from the real sample. The electrochemical analysis was studied by DPV method in the following conditions: initial potential − 0.7 V, end potential − 0.1 V, modulation amplitude 50 mV and scan rate 50 mVs⁻¹
