Fig. 3: Construction and experimental results of sensor array based on different reporter pairs.

a Schematic diagram of SA1. Pattern recognition of proteins using SA1 ([CA] = [CD] = 1.0 μM, [dye] = 1.0 μM). b Fluorescence response patterns of SA1 against various proteins (23.8 μg/mL for each protein). The order of colored symbols from top to bottom in the legend corresponds to the column order of histogram from left to right. c Canonical score plot for the two factors of simplified fluorescence response patterns obtained from LDA with 95% confidence ellipses. All experiments were performed in water (pH = 6.53) and pH only slightly changed after the addition of proteins (Supplementary Table 2). The fluorescence spectra of dyes were recorded and kept almost unchanged in the presence of NaClO4 (up to 27.5 mM, Supplementary Fig. 26) in order to exclude the effect of ionic strength. Error bars in b represent mean ± s.d. (n  =  6 independent experiments).
