atmospheric pressure plasma

Atmospheric pressure plasma is a state of matter where gases are energized at normal air pressure, creating a mixture of ions, electrons, and neutral particles. Unlike traditional plasma found in stars or specialized industrial settings, this type operates at or near atmospheric conditions, making it practical for everyday applications. It is used in sterilization, surface treatment, and waste reduction because it can modify materials' surfaces or kill germs effectively. The plasma is generated by applying electrical energy to gases, producing reactive species that interact with solids, liquids, or biological surfaces without needing a vacuum environment.
