Fig. 2: Construction of the sensor array and the discrimination of intracellular bacteria.

a Chemical structures of the employed azocalix[4]arenes and fluorescent indicator. b Fluorescence response patterns of the sensor array against various intracellular bacteria and the blank macrophage. Data are presented as mean ± SD, n = 5 biological replicates. c Canonical score plot for the two factors of simplified fluorescence response patterns obtained from LDA with 90% confidence ellipses, n = 5 biological replicates. d Canonical score plot for the mixtures of intracellular SA and LM with 90% confidence ellipses, n = 5 biological replicates. e Canonical score plot for intracellular bacteria from peritoneal fluid samples with 90% confidence ellipses, n = 5 biological replicates. Source data are provided as a Source Data file.
