To activate toehold switch, an amount of energy is needed to open the toehold switch hairpin. The Switch MFE reflects the difficulty for the toehold switch unwinding process. We assume that the more negative the Switch MFE, the harder for the unwinding to take place, and hence a lower leakage. | To activate toehold switch, an amount of energy is needed to open the toehold switch hairpin.

● ΔMFE is defined as MFE of the switch-trigger duplex RNA minus (switch RNA MFE + trigger RNA MFE). | ● ΔMFE is defined as MFE of the switch-trigger duplex RNA minus (switch RNA MFE + trigger RNA MFE). |
