Summary of ionic rectification factor on single-step modified DWCNT-dye membrane
Concentration Rectification factor
(mM) Potassium ferricyanide NDS Sodium benzenesulfonate
10 7.2 ± 0.3 3.1 ± 0.3 2.4 ± 0.2
50 6.4 ± 1 2.0 ± 0.1 2.0 ± 0.1
100 5.6 ± 1 2.3 ± 0.1 1.7 ± 0.1

Rectification factor was calculated by the ratio of ionic transport current at ±0.6-V bias. Linear scan was from −0.60 to +0.60 V with the scan rate at 50 mV/s.
