Exposure of Bacterial Biofilms to Electrical Current Leads to Cell Death Mediated in Part by Reactive Oxygen Species
Fig 5
Detection of reactive oxygen species (ROS) using nitroblue tetrazolium.
Samples not exposed to current (shown as 0 μA) were compared with those exposed to 200 μA direct current (DC) after 5 and 10 minutes. A. ROS production in S. aureus *p = 0.0088; B. S. epidermidis *p = 0.0088 **p = 0.012; and C. P. aeruginosa *p = 0.009, compared with control.
