Figure 4: Fluorescence monitoring of the structural changes of DNA nanoarchitectures.
From: Interlocked DNA nanostructures controlled by a reversible logic circuit
(a) Fluorescence signal of RG/BHQ1 FQ system in response to the structural changes. The toehold strand displacement is reflected by an increase in the RG fluorescence, while a decrease indicates the reverse process. (b) Kinetic data for the toehold-mediated release experiment in the working solution at different temperatures. The addition of ROs induces a sharp increase in the fluorescence in about 1 h at 37 °C, while in about 3 h at 25 °C (inset).
