“…[147,148] Moreover, it has been demonstrated that nitric oxide (NO) generated by topical application of DBD over cause changes in microcirculation up to 6000-8000 µm on treated skin areas. [149] Dried AM with a thickness of approximately 20 µm [150] will therefore lie within the penetration range of CAP and should not require lengthy exposure times.…”

“…[159,160] The interplay of these parameters could yield sufficient plasma density and composition, or conversely might change the treatment outcome; causing inconsistency in sterilization cycles. [161] For instance, operational parameters such as ion and UV flux, electric field and gas flow might not have direct influence on the antibacterial efficiency, while other factors related to the method and conditions of application such as distance from the plasma nozzle and exposure time have a distinct influence on treatment efficiency.…”

Tissue products are susceptible to microbial contamination from different sources, which may cause disease transmission upon transplantation. Terminal sterilization using gamma radiation, electron‐beam, and ethylene oxide protocols are well‐established and accepted, however, such methods have known disadvantages associated with compromised tissue integrity, functionality, safety, complex logistics, availability, and cost. Non‐thermal (cold) atmospheric pressure plasma (CAP) is an emerging technology that has several biomedical applications including sterilization of tissues, and the potential to surpass current terminal sterilization techniques. This review discusses the limitations of conventional terminal sterilization technologies for biological materials, and highlights the benefits of utilizing CAP.

“…However, when the distance between the plasma jet nozzle was too small, the flow of oxygen gas from the nozzle was almost blocked by the fabric and the oxygen gas could only be bounced off the surface and flew out in a more parallel to the fabric surface direction, which greatly recued the effectiveness of the treatment [5]. On the hand, when the distance was too long, the velocity and the activity of the active species in the plasma jet greatly decreased when reaching the surface of the fabric and thus was not effective either [5]. In addition, when the jet distance was too long, the active species in plasma would collide with the surrounding air molecule and hence reduced their reactivity.…”

Abstract-Titanium dioxide (TiO 2 ) has been found feasible for improving the wrinkle resistant of cotton fabric. In this paper, plasma treatment was used as a pretreatment process to enhance the application of TiO 2 in wrinkle resistant treatment of cotton fabric. The relationship between plasma pretreatment process parameters including (i) treatment speed, (ii) oxygen flow rate; and (iii) jet distance were studied through orthogonal array testing strategy (OATS). Based on the OATS, the optimum condition for plasma pretreatment of cotton fabric before 0.2% TiO 2 treatment could be obtained and also their relative importance can be found. The optimum condition was: (i) treatment speed = 15 mm/s; (ii) oxygen flow rate = 0.3 L/min. and (iii) jet distance = 5 mm and the order of importance was oxygen flow rate followed by jet distance and treatment speed.

“…In addition, the treatment on the material surface mainly depends on the collisions between the processing materials and high-energy electrons, excited or metastable particles in the plasmas. The material surface is modified for tens of nanometers, and without an obvious effect on their physical structures and internal characters [1][2][3][4].…”

Surface modification of fiber fabric sometimes needs a large volume of cold plasma to improve its efficiency. This experimental study is based on the treatment of polyamide 66 (PA66) fabrics using large contact-area glow-like plasma, which are produced in the atmospheric air without any dielectric barriers. The atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS) are adopted, respectively, to detect the surface changes in physical microstructure and the variations in the type and quantity of chemical functional groups. The results show that the PA66 fabric surface will be etched remarkably by the glow-like plasma, and the surface roughness and the surface energy are augmented. On the surface of the processed PA66 fabrics, the oxygen-containing functional groups' content rises together with the decrease on the total primary C-C and C-N bonds. After 30 seconds of sterilization by the glow-like plasmas, most of the bacterial colonies on the fabric vanish. The effectiveness of this kind of plasma treatment could last for three days in a sealed environment.
