Fig. 2. Normalized CV peak current varies with NaCl concentration across surface-tethered ELP variants.

Fig. 2

Normalized peak current height versus salt (NaCl) concentration obtained by CV for ELPV3 (black triangles show data average, black line shows model), ILELPV3 (red squares show data average, red line shows model), ILELPIV2 (blue rhombus show data average, blue line shows model), ILELPI2V (green parallelograms show data average, green line shows model), and ILELPI3 (purple stars show data average, purple line shows model). The normalized peak current height of CV data was averaged for different numbers of repeats  (Supplementary Table 1 reports the precise number of replicates per data point shown in the plot with each repeat being done on a single sensor) and modeled via Eq. (1). CV was performed between 0 to 0.7 V vs. a silver pseudo-reference electrode with a scan rate of 50 mV/s. Error bars represent standard error.
