Fig. 2. Specificity of three candidate aptamer-CDs/GO systems towards P. aeruginosa and against Pseudomonas putida, Enterococcus faecalis, Clostridium perfringens, E. coli, B. subtilis, and S. aureus. * (P < 0.05), ** (P < 0.01): significant difference between two groups. F = fluorescence intensities excited from the aptamer-CDs/GO system in the presence of bacterial cells. F0 = the fluorescence intensities excited from the aptamer-CDs/GO system in the absence of bacterial cells.
