Nonthermal biocompatible plasma (bioplasma) sources and their characteristics operating at atmospheric pressure have been introduced and overviewed for plasma bioscience and medicines, especially used in Plasma Bioscience Research Center (PBRC), Korea. The electron temperature and density have been measured, respectively, by the atmospheric collisional radiative model and Stark broadening method in this experiment. The electron temperatures and plasma densities are measured to be 0.2 ~ 0.7 eV [1] and 1×1014 ~ 2×1015 cm-3, respectively, for the nonthermal bioplasma jet and DBD plasma sources in PBRC. Herein, we have also introduced the basic generation mechanism of reactive hydroxyl radical OH species and hydrogen peroxide H2O2 by plasma-initiated ultraviolet photolysis of water[1] inside the biological solutions, which are main species of interactions with microbial[2] and mammalian cells resulting in apoptotic cell death [3].
