Guest Editorial The Second Special Issue on Atmospheric Pressure Plasma Jets and Their Applications
I
T HAS been about two and a half years since the publication of the first IEEE Special Issue dedicated to the “Atmospheric Pressure Plasma Jets and Their Applications” in November 2012. Fig. 1 shows the publications on the atmospheric pressure plasma jet (APPJ) in the last decade from Web of Science. It clearly shows that this topic has been significantly grown in the past one decade and is still growing. As we know, one of the emerging applications of plasma jets is plasma medicine, which is another one of the fastest growing field in low-temperature plasmas in the past decade. A plasma jet can directly interact with bio objects or the afterglow of the plasma jet interacts with bio objects as illustrated in Fig. 2. When a plasma jet is used to treat bio objects, the bio objects are covered by a thin layer of liquid in most cases. When the afterglow of a plasma jet interacts with bio objects, the main reactive species are relative long lifetime radicals such as OH, O, O3 , NO, and some metastable molecular such as O2 (a) and N2 (A) (these metastable state molecular does not seem to play a direct role in the inaction with bio objects, but they play an important role in the generation of radicals such as OH, O, and O3 ). On the other hand, when a plasma jet directly interacts with bio objects, besides the relative long lifetime radicals mentioned above, the short-time radicals including electrons, various ions, and some excited species could also play some roles in the treatment of bio objects. For pulsed discharge plasma, the relative long lifetime radicals also play important role for the treatment of bio objects even for the direct treatment. As can be seen from Fig. 2, research on plasma treatment of bio objects can be simply divided into four branches, including: 1) plasma physics; 2) plasma chemistry; 3) solution chemistry; and 4) biochemistry. After one decade’s studies, we know much more about the physics of plasma jets, including the dynamics of plasma bullets, the role of photoionization, the role of residual charges, and so on. Thanks to the modern computer simulation technology and the advanced plasma diagnostics methods such as Laser-induced fluorescence, Twophoton absorption laser-induced fluorescence, Cavity ring down spectroscopy, Ultraviolet-visible absorption, Blackbody absorption, and Fourier-transform infrared, we have also made significant progress inplasma chemistry in the afterglow.

On the contrary, we only know a little bit about solution chemistry and even less about biochemistry, which are very complicated and are actually beyond the knowledge of most plasma scientists. However, to understand the effect of plasma jets on bio objects, we need to acquire knowledge in these fields, on the one hand. On the other hand, it is actually more important and essential for us to reach out in the next decade, to recruit researchers who have a background in solution chemistry, radical chemistry, biochemistry, and molecular biology, and medical doctors to the field of plasma medicine, which will definitely significantly drive us to make progress in plasma medicine. This Special Issue reflects the latest progress in APPJs and their applications. A total of 12 papers in this Special
