Figure 6.
Typical volt–ampere characteristics recorded for one and the same nanowire on the SOI-NW chip with n-type conductivity. Measurement conditions: 1 mM PPMB; Vg = 0 – 60 V, Vds = 0.2 V; the oDNA probe probe_1 was covalently immobilized on the nanowire. The VACs were recorded before the nanowire functionalization (blue curve), after the nanowire silanization (pink curve), and after its sensitization with oDNA probes (violet curve).
