This study focuses on the development of a nonthermal newlineplasma (NTP) dielectric barrier discharge (DBD) reactor. The primary objective of this newlinetechnology is to enhance the breakdown of volatile organic compounds (VOCs) and to promote newlinethe development of environmentally suitable methods for modifying surfaces. The NTP-DBD newlinereactor employs both parallel plate and coaxial configurations to generate electrical discharges. newlineWithin the reactor, the electric field accelerates free electrons, resulting in both elastic and newlineinelastic collisions. In elastic collisions, electrons retain most of their kinetic energy. Conversely, newlineunder intense electric fields, electrons gain enough energy to cause inelastic collisions, newlinetransferring a substantial portion of their kinetic energy to the molecules involved. newlineIn the context of implantation, the surface of a biomaterial device serves as the primary interface newlinewith living tissues, whereby water molecules are the first to come into touch. To achieve the best newlinepossible interaction between cells and biomaterials, it is crucial to enhance the efficient newlineattachment of cells to the substrate. Key factors influencing enhanced cell-surface interactions newlineinclude surface topography, chemistry, and free energy. The cold or non-thermal plasma newlinetechnique has gained prominence as an effective, efficient, and economical method for newlinemodifying the surfaces of polymeric composites. This technique offers several advantages: it newline
