Fundamentals of Cold Plasma Technology

Understanding the fundamentals of cold plasma technology is akin to discovering the building blocks of an enigma. Cold plasma, often referred to as a ‘fourth state of matter,’ exists in a state where energy is absorbed mainly by electrons rather than by molecules, making it vastly different from the hot plasmas found in stars or fire.^[7] Comparing cold plasma to a gentle breeze that holds the power of a hurricane captures its essence and potential when harnessed correctly. Cold plasma operates at near-room temperature, and its non-thermal nature makes it suitable for applications that traditional high-temperature plasmas would damage.^[8] With a palette of reactive substances like ions, free radicals, and UV photons, cold plasma can be meticulously controlled and tailored, allowing for precise application across fields ranging from delicate food items to sensitive medical treatments.^[9]

Definition and Characteristics of Cold Plasma

Cold plasma is defined as a partially ionized gas consisting of ions, electrons, and neutral particles, which exists under low-temperature conditions. Unlike thermal plasma, where higher temperatures are necessary for ionization, cold plasma can be generated at atmospheric pressure and low temperatures, typically not exceeding 40 °C.^[10] The widespread application of cold plasma stems from its ability to ionize gases using electromagnetic fields, such as radiofrequency (RF) or microwave energy, creating a versatile technology that operates under low-energy conditions. This capability allows for the treatment of heat-sensitive materials without causing damage.^[11]

When we think of cold plasma’s characteristics, several key features emerge:
