Fig. 7

Variation of charge-transfer resistance with time. Comparative change in charge-transfer resistance with time measured from impedance response during hybridization of cDNA to probe-DNA attached directly to the gold surface (red circle) and probe-DNA attached to VASWCNTs on the gold surface (black square). Impedance measurements are done in the presence of 1 mM [Fe(CN)6]3−/4− and 0.1 M aqueous KCl solution
