Canonical score plot for the UCNPs@COPs-based fluorescent sensor array against the bacteria mixtures of E. coli and S. aureus with different ratios (100:0, 80:20, 60:40, 50:50, 40:60, 20:80, and 0:100), respectively in physiological saline. In each case, a bacteria concentration of OD600 = 0.1 was used. Each point represents the response pattern for single bacterial mixtures to the array
