Fig. 6: Construction, theoretically model, and experimental results of sensor array based on adjusting reporter pair ratio.

a Schematic diagram of the theoretical model of sensor array formed by adjusting the reporter pair ratios. b Schematic simulated titration curves for direct binding and competitive binding. c Fluorescence response patterns of the simulated sensor array. d Schematic diagram of SA7. Pattern recognition of proteins using SA7 ([GC5A] = [CD] = 0.8 μM, 1.0 μM, 1.2 μM, and 1.4 μM, [AlPcS4] = 1.0 μM). e Fluorescence response patterns of the sensor array against various proteins (23.8 μg/mL for each protein). f Canonical score plot for the two factors of simplified fluorescence response patterns obtained from LDA with 95% confidence ellipses. Error bars in c, e represent mean ± s.d. (n  =  6 random numbers and independent experiments). The order of colored symbols from top to bottom in the legend corresponds to the column order of histogram from left to right in c, e.
