Abstract:Recently developed excitation frequency‐controlled cold atmospheric pressure plasma has shown its efficacy in producing tunable effects with different excitation frequencies in terms of reactive species generation and cancer cell death. This study investigates the electron number density of plasma produced at 11 kHz excitation from stark broadened Hα line, discharge characteristics through simultaneous recording of voltage‐current signals, and high‐speed images of the discharge zone. Malignant breast cancer ce… Show more
