a Signal patterns of the relative fluorescence intensity variety ((Fi − F0)/F0) of three kinds of UCNPs@COPs probes in the presence of seven different bacteria (OD600 = 0.5). All values represent the average of six replicates. b Canonical score plot for the response patterns of bacteria obtained from LDA. Each point represents the response pattern for single bacterial species to the array
