What Researchers Did
This review examined the formation, mechanisms of action, and antimicrobial applications of reactive oxygen species (ROS), including bactericidal antibiotics and nonpharmacological methods.
What They Found
Researchers found that four major reactive oxygen species (ROS) – superoxide, hydrogen peroxide, hydroxyl radical, and singlet oxygen – exhibit varying antimicrobial activities. While superoxide and hydrogen peroxide can be detoxified by endogenous antioxidants, hydroxyl radical and singlet oxygen are highly toxic and cannot be enzymatically detoxified. Antimicrobial strategies leveraging ROS include bactericidal antibiotics and nonpharmacological methods like photodynamic therapy, titanium dioxide photocatalysis, cold plasma, and medicinal honey.
