Figure 3

(a) The 𝑉 - l n 𝐼 curve of adenosine from 0 V to 3.0 V with a step of 0.2 V, and the current curve of non-load electrodes system from 0.0 V to 2.0 V with a step of 0.1 V. (b) Four distinguishable 𝑉 - l n 𝐼 curves of four nucleotides, A, C, G, T, respectively. All of which express linear relationship from 2.0 V to 2.6 V with the same step of 0.2 V. At most voltages, they keep a difference of one or two orders to each other.
