(A) Comparison of reaction kinetics of the proposed CHA-DNAzyme strategy and CHA strategy. (B) The F/F0 ratio of the proposed CHA-DNAzyme strategy and CHA strategy at different reaction time (N = 3). The concentration of miRNA-21 was 5 nM. F represents the fluorescence intensity at different reaction time points and F0 represents the initial fluorescence intensity.
