1. Introduction
Bioplasma, often referred to as Cold Atmospheric Plasma (CAP), is a partially ionized gas containing electrons, ions, reactive oxygen and nitrogen species (RONS), electromagnetic fields, and UV photons. Generated at near room temperature, CAP maintains a non-equilibrium state where electrons are highly energized while the bulk gas remains cool—a property that enables its safe application to biological tissues without causing thermal damage Nature+15MDPI+15ResearchGate+15.
Its unique features make bioplasma a potent tool across medicine, agriculture, environmental science, and industry. Additionally, Plasma-Activated Water (PAW)—liquid treated with CAP—is increasingly recognized as a practical, versatile biomaterial. There are many companies offering Bioplasma Services.

2. Science & Mechanisms
2.1. Non-Thermal, Cold Plasma Defined
Non-thermal plasma (or cold plasma) is characterized by electron temperatures of tens of thousands Kelvin, while ions, atoms, and the gas remain near ambient temperature. CAP falls under this category and can be operated at atmospheric pressure, making it practical for direct use on living organisms or surfaces Frontiers+3ScienceDirect+3Frontiers+3MDPIWikipedia.
2.2. Generation Methods
Common CAP generation techniques include:
-
Dielectric Barrier Discharge (DBD): Electrodes separated by a dielectric barrier produce micro-discharges in air or gas.
-
Plasma Jets: Often powered by helium or argon, these jets generate a narrow plasma plume directed onto a target.
-
Piezoelectric Radiofrequency Generators: Hand-held devices that ignite plasma via RF at room temperature MDPIWikipediaFrontiers.
2.3. Composition & Reactive Species
CAP generates a dynamic balance of:
-
Short-lived radicals: OH⋅, O⋅, NO⋅, singlet oxygen
-
Long-lived species: H₂O₂, NO₂⁻, NO₃⁻, O₃ Wikipedia+11Frontiers+11BioMed Central+11MDPI+15SpringerLink+15BioMed Central+15
Together with electric fields and UV emissions, these species exert biological effects like oxidative stress, membrane modification, DNA damage, and immune modulation ResearchGate+12Wikipedia+12MDPI+12.
