Microbial cell component via oxidative damage

Oxidative damage to microbial cell components is an antimicrobial mechanism where reactive oxygen species (ROS) generated by drugs or materials (such as certain inorganic compounds or disinfectants) disrupt essential cellular structures. ROS can oxidize lipids in cell membranes, proteins, and nucleic acids, leading to damage that impairs microbial viability or causes cell death. The process is broad, affecting many molecular targets within the cell, and is not limited to a single, well-defined molecule or receptor. Bacteria and other microbes have evolved stress response systems and repair mechanisms to counteract oxidative damage, but overwhelming oxidative stress leads to immediate or eventual cellular dysfunction and death.
