Abstract Cancer remains a leading cause of mortality worldwide, necessitating novel, effective, and selective therapies. Cold Atmospheric Plasma (CAP) generates reactive species that can selectively kill tumor cells while sparing healthy tissue. We developed multipoint Surface Dielectric Barrier Discharge (SDBD) plasma system capable simultaneously treating all wells in 24-well plate, enhancing experimental throughput consistency. investigated both direct treatment indirect effects via...
Abstract This research explores the synergistic application of Dielectric Barrier Discharge (DBD) and Gliding Arc Plasma Jet (GAPJ) in a Hybrid (HPD) setup for enhanced water activation. The HPD system demonstrated balanced sustained generation reactive oxygen nitrogen species (RONS), maintaining efficiency at higher specific input energy (SIE) values. Comparative analyses with DBD GAPJ systems highlighted superior performance generating RONS modifying water’s molecular structure. Key...
