Example plasmaclave devices are shown for using a plasma to sterilize objects or equipment (e.g., medical instruments, surgical devices, food preparation utensils, etc.) placed inside the plasmaclave devices. In some embodiments, the plasmaclave device includes fixed magnets, steering coils, and a high voltage electrode for generating a plasma field and controlling where the plasma field is focused, so that the plasma field is rapidly scanned over a target surface. In some embodiments, the plasmaclave device includes a high voltage coil, a motor, and a blade electrode for generating a plasma field and spinning the blade electrode, so that the plasma field is rapidly scanned over a target surface.
