What Is Cold Plasma? Complete Guide to Revolutionary Medical Technology

July 4, 2025

Understanding Cold Plasma Technology

What Makes Cold Plasma Different from Traditional Plasma?

Cold plasma represents a unique state of matter where gas molecules become partially ionized without generating excessive heat. This non-thermal plasma contains a complex mixture of reactive oxygen species (ROS), reactive nitrogen species (RNS), electrons, ions, and electromagnetic radiation^[3].

The key distinction lies in the temperature differential between electrons and heavy particles. While electrons reach temperatures exceeding 10,000K, the gas temperature remains close to room temperature, creating what scientists call “non-equilibrium plasma”^[4].

How Is Cold Plasma Generated?

Cold plasma generation typically involves applying electrical energy to gases at atmospheric pressure. The most common method uses dielectric barrier discharge (DBD), where high-voltage alternating current creates plasma between electrodes separated by a dielectric material.

The process involves three critical steps:

Gas Ionization: Electrical energy breaks molecular bonds in air or noble gases
Reactive Species Formation: Ionized particles interact with surrounding molecules
Controlled Delivery: The plasma stream is directed toward the treatment area

Scientific Mechanisms Behind Cold Plasma Therapy

Reactive Oxygen and Nitrogen Species Production

Cold plasma generates numerous bioactive compounds that interact with biological systems. The primary therapeutic agents include:

Reactive Oxygen Species (ROS):

Hydroxyl radicals (OH)
Hydrogen peroxide (H₂O₂)
Superoxide anions (O₂⁻)
Ozone (O₃)

Reactive Nitrogen Species (RNS):

Nitric oxide (NO)
Nitrogen dioxide (NO₂)
Peroxynitrite (ONOO⁻)
Nitrous acid (HNO₂)

These reactive species trigger various cellular responses depending on their concentration and exposure time^[5]. Low concentrations promote cell proliferation and tissue healing, while higher concentrations can induce controlled cell death in pathogenic organisms or abnormal tissues.

Nitric Oxide vs Reactive Oxygen Species

One of the pioneering medical devices applying cold plasma therapy is the Mirari Cold Plasma system, developed by General Vibronics and brought to market by Mirari Doctor. It utilizes nitric oxide (NO) instead of traditional ROS-based systems to promote safe, non-thermal healing^[6].

Nitric oxide offers several advantages over traditional ROS-based approaches:

Enhanced biocompatibility: NO naturally occurs in the body as a signaling molecule
Reduced oxidative stress: Less cellular damage compared to high-ROS systems
Improved tissue healing: NO promotes vasodilation and angiogenesis
Better patient tolerance: Minimal side effects and discomfort

Antimicrobial Effects

Cold plasma exhibits broad-spectrum antimicrobial activity against bacteria, viruses, fungi, and even antibiotic-resistant strains like MRSA^[8]. The antimicrobial mechanisms involve:

Cell membrane disruption: ROS damage bacterial cell walls
DNA damage: Reactive species interfere with genetic material
Protein denaturation: Essential enzymes become non-functional
Biofilm destruction: Penetration through protective bacterial layers

Dermatological Conditions	1-5 minutes	Variable	Improved skin texture and healing

Safety Considerations and Contraindications

Is Cold Plasma Safe for All Patients?

Cold plasma therapy is generally considered safe when performed with properly calibrated equipment and appropriate protocols. However, certain precautions must be observed^[10].

Safe for most patients when:
