Biological tissue ablation via direct current plasma discharge

Biological tissue ablation via direct current plasma discharge" refers to the use of a **plasma generated by a direct electrical discharge**—specifically using a continuous potential difference between electrodes—to physically destroy or modify biological tissues. This is not a molecular target such as an enzyme, receptor, or transporter; rather, it is a **medical technique** that employs the unique properties of plasmas for clinical purposes. Direct current plasma discharges can generate highly energetic electrons and ions at atmospheric pressure. When applied to biological tissues, these plasmas can induce cell death through both physical mechanisms (localized heating and disruption) and chemical mechanisms (generation of reactive species). Applications include tumor/cancer cell destruction, sterilization in medical settings, treatment of skin diseases and wounds, dental procedures, and other forms of minimally invasive surgery[3][4]. The method is part of the broader field known as "plasma medicine." Because this entry describes an **application/technique** rather than a discrete molecular entity or therapeutic target classically defined in pharmacology or molecular biology—and because it lacks specificity regarding any single molecule—it should be flagged as incorrect for structured drug-target databases. If you need information about specific molecules involved in the cellular response to plasma exposure—or about particular types/subtype s of gas/plasma discharges used in medicine—please clarify your request.
