Adapted with permission from reference [198]. Figure 2.5 Mechanisms of toxicity of nano-particles (NP) against bacteria. NP and their ions (e.g., silver and zinc) can produce free radicals, resulting in induction of oxidative stress (i.e., reactive oxygen species; ROS). The produced ROS can irreversibly damage bacteria (e.g., their membrane, DNA, and mitochondria), resulting in bacterial death. Adapted with permission from reference [127].
