Abstract A nanocomposite of polyaniline/graphene (PAN/GN) was prepared using reverse-phase polymerization. The nanocomposite material was dropcast onto a glassy carbon electrode (GCE). Then, a single-stranded DNA (ssDNA) probe for HIV-1 gene detection was immobilized on the modified electrode, and the negative charged phosphate backbone of the HIV-1 was bound to the modified electrode surface via π-π∗ stacking interactions. The hybridization between the ssDNA probe and the target HIV-1 formed… Expand
