Thermal reversibility of the Cat^hyb to Cat^mec interconversion. a) Time‐dependent change of fluorescence intensity of the mixture of ring A‐G9 and ring B‐G9 (black, 100 nm) and the Cat^mec‐G9 (red, 100 nm) in DC buffer (S.D., n=3). b) Diagram of the temperature cycling between 42 °C and 60 °C. c) Fluorescence intensity of 6‐FAM (red), Cat^hyb‐G9 (black), and the quenched negative control (blue) at 42 °C and 60 °C (S.D, n=3).
