Abstract: The Floating Electrode-Dielectric Barrier Discharge (DBD-FE) was designed for production of cold atmospheric plasma to be used in biological applications. The designed Floating Electrode-Dielectric Barrier Discharge device was consist of two main parts: FE-DBD probe and high voltage power supply. Two types of probes were used according to the applications of the system: small probe of diameters 2-5 mm this is suitable for in vitro experiments and large probes of diameters 10-20 mm for in vivo applications. The HV power supply was designed, especially, to fid FE-DBD probe by alternative high voltage it can provide a variable Voltage (0-25 kV) and variable frequency (0-30 kHz). The device was designed in a way to be is able to change the output power of the produced cold plasma of five different level (1, 2, …, 5) this is done by the main switch power fixed in the interface of the device. The output power was ranged 6-57 W and temperature of the produced plasma ranged 32-45°C, therefore, it is suitable for the biological applications. A cold plasma produced by the device was tested by exposure a natural tissue to the plasma it is found that it do not cause any toxicity to the natural tissue. Laboratory study was carried out on tissue culture in a circumvented circumference using breast tissue for tissue culture it was found that the cold plasma treatment would not cause any damage for, liver, kidney and spleen tissue. In vitro experiments, the cytotoxicity was calculated normal tissue (ref) under different doses of CAP, 5, 10 and 15 sec it was found the ref exhibition was very little or no cytotoxicity.
