Kill rates of ZIF-67 against pathogenic bacteria. Bacterial suspensions of A. baumannii 17978, P. aeruginosa PA01, and S. aureus 29213 were exposed to ZIF-67 at 850 μg ml⁻¹, chloramphenicol (Chl) at 12 μg ml⁻¹ or PBS for 4 h at 37 °C. Cell viability was determined by spotting samples of serial 1:10 dilutions of the bacterial suspensions on MH agar plates at different exposition times
