Biomedical applications and diagnostics of atmospheric pressure plasma

Non-thermal atmospheric pressure plasma sources for biomedical applications

It was presented that various types of non-thermal atmospheric pressure plasma sources operated with low frequency(~kHz) or microwave frequency feeding argon or helium gas, or in the ambient air could be used for the treatment of cancer cells, sterilization, tooth whitening, and blood coagulation. The antibody-conjugated GNPs enhanced to kill cancer cells exposed to plasmas. The plasmas treatme...

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...

Aiaa 99-3604 Diagnostics of an Atmospheric Pressure Plasma Jet

Broadband ultraviolet absorption spectroscopy is employed to measure absolute number density of C2 and CH radicals in the boundary layer of an atmospheric DC plasma assisted chemical vapor deposition (CVD) system. High spatial resolution (125 μm) is achieved by using a spatial filter and a ultra-bright argon mini-arc light source. The spectra of D Σu←X Σg electronic transition of C2 and C Σ←X ∏...

Cold Atmospheric Plasma (CAP) Nanotechnology Technique for Biomedical Applications

Cold atmospheric plasma (CAP) is an ionized gas where the ion temperature is close to room temperature as opposed to typical high-temperature laboratory plasmas. It can be carried out in the presence of Helium (He) with a high voltage. CAP is composed of various electrons, positive/negative ions, reactive oxygen species (ROS), reactive nitrogen species (RNS), radicals, excited molecules, energe...
