Figure 4. Identifying an outlier gate.

(a) Logic circuit diagram, seesaw circuit diagram and experimental data of a two-layer logic circuit. (b) Measuring the effective concentrations of the gate species. Three independent circuits were used to measure the effective concentrations of two gates fully triggered by x₁ and x₂, respectively, comparing with the effective concentration of x₃ (using signal strand w_18,53). (c) Experimental data of the two-layer logic circuit using adjusted nominal gate concentration. 1 × =100 nM.
