Fig. 5From: Sensitive and Selective Detection of HIV-1 RRE RNA Using Vertical Silicon Nanowire Electrode Array(a) Differential pulse voltammograms obtained at HIV-1 RRE RNA-coated VSNEA at different RNA concentrations (0, 1, 3, 5, 10, and 20 fM). The inset shows linear regression obtained from difference between the DPV signals of RNA functionalized VSNEA in the presence and absence of target. (b) DPV results at V vs Ag/AgCl in the range 0.21-0.27Back to article page
