Representative fields captured by epifluorescent microscopy during plasma membrane integrity analysis; green and red fluorescent marks correspond to cells recognized as live and dead, respectively. The images (60X magnification) correspond to a PBS suspension containing 106 cells mL−1 stained with LIVE/DEAD BacLight Bacterial Viability kit before (a) and after (b) exposure to copper ions
