Nonthermal Plasma Jet for Biomedical Applications

Effects of a Nonthermal Atmospheric Pressure Plasma Jet on Human Gingival Fibroblasts for Biomedical Application

Nonthermal atmospheric pressure plasma jets (APPJ) have been developed and applied in biomedical research as a cancer treatment or bacterial sterilization. However, the drawback of APPJ on normal oral cells during plasma treatment and underlying cell death mechanisms have not been studied and clearly explained, although there is known to be an influence from reactive oxygen species (ROS). Hence...

Atmospheric Pressure Single Electrode Argon Plasma Jet for Biomedical Applications

Atmospheric pressure single electrode argon /oxygen plasma jet has been generated between a high-voltage electrode and the surrounding room air for treating thermally sensitive materials is reported. The discharge has been characterized by electrical and optical emission spectroscopic technique. The microplasma jet device operated by an electrical power less than 10 W exhibited a long plasma je...

Wearable Plasma Pads for Biomedical Applications

A plasma pad that can be attached to human skin was developed for aesthetic and dermatological treatment. A polyimide film was used for the dielectric layer of the flexible pad, and high-voltage and ground electrodes were placed on the film surface. Medical gauze covered the ground electrodes and was placed facing the skin to act as a spacer; thus, the plasma floated between the gauze and groun...
