(a) Schematic illustration of tailoring the well-defined polymeric Q-PGEDA-OP/TPE antimicrobial system for the bacterial detection and the antibacterial activity of the Q-PGEDA-OP prior to and after hydrolysis. (b) Photographs of colony-forming units (CFU) for AMOr S. aureus and AMOr E. coli treated with AMO or Q-PGEDA-OP/TPE on the LB agar plate; CFU ratio of (c) AMOr S. aureus and (d) AMOr E. coli. Note: Asterisk (*) indicates significant differences (p < 0.05) between every two groups. (e) SEM images of AMOr S. aureus and AMOr E. coli treated with PBS, Q-PGEDA-OP, and Q-PGEDA-COOH.
