Fig. 7

DPV profiles of ssDNA/nano-onion (NO)/MoS2/indium tin oxide (ITO) and ssDNA/MoS2/ITO + non-complementary (NC) DNA (5 ng/ml). Figure a, c and d and Figure b, e, and f displays the sensing potential for HPV-16 and HPV-18, respectively. Figure a and b display average peak current calibrated from independent measurement of five distinct electrodes. Figure c through f showcase the DPV profile of a single electrode in sequential mode: without DNA, following probe DNA chemisorption, and after addition of noncomplimentary DNA for both NO/MoS2 nanosheet composite and MoS2 nanosheet electrodes
