大气压低温等离子体射流的时间分辨成像显示，在放电周期中，“等离子体子弹”的发展，以高达2 ×104 m/s的速度移动。将该等离子体射流应用于细菌大肠杆菌，并评估其活力。非活性区域为直径约为8 mm的圆形，远大于等离子体射流的直径（约1 mm）。需要进一步的研究来充分了解等离子体子弹放电行为和机制，使E。大肠杆菌由于暴露于等离子体射流而不能存活。
Time-resolved imaging of an atmospheric-pressure low-temperature plasma jet showed the development of a “plasma bullet” during the discharge cycle, moving at velocities up to 2 ×104 m/s. This plasma jet is applied to the bacterium Escherichia coli, and viability is assessed. The region of nonviability is circular with a diameter of about 8 mm, which is much larger than the diameter of the plasma jet (~ 1 mm). Further investigations are needed to fully understand the plasma bullet discharge behavior and the mechanisms rendering E. coli nonviable due to exposure to the plasma jet.
