使用微波等离子体进行灭菌是相对较新的。这种方法的优点是相对较低的温度，节省时间和无毒的性质，与传统的方法，如热和气体处理，辐射。研究了大气压下微波诱导氩等离子体对污染有细菌、真菌等微生物的材料的灭菌效果。设计了一种低成本、高可靠性的2.45 GHz波导型微波等离子体发生器。该系统由1 kW磁控管电源、WR-284铜波导、包括调谐部分的施加器和喷嘴部分组成。使用六种细菌和真菌菌株进行灭菌试验。结果显示，无论菌株如何，本研究中使用的所有细菌均在20秒内完全灭菌，所有真菌均在1秒内灭菌。这些结果表明，这种灭菌方法易于使用，所需时间明显少于其他传统方法和已建立的等离子体灭菌方法，并且无毒。它可用于医疗和牙科诊所以及实验室环境中的灭菌领域。(C)2003年，美国物理学会。
The use of microwave plasma for sterilization is relatively new. The advantages of this method are the relatively low temperature, time-savings and its nontoxic nature, in contrast to traditional methods such as heat and gas treatment, and radiation. This study investigated the sterilization effects of microwave-induced argon plasma at atmospheric pressure on materials contaminated with various microorganisms, such as bacteria and fungi. A low-cost and reliable 2.45 GHz, waveguide-based applicator was designed to generate microwave plasma at atmospheric pressure. This system consisted of a 1 kW magnetron power supply, a WR-284 copper waveguide, an applicator including a tuning section, and a nozzle section. Six bacterial and fungal strains were used for the sterilization test. The results showed that regardless of the strain, all the bacteria used in this study were fully sterilized within 20 seconds and all the fungi were sterilized within 1 second. These results show that this sterilization method is easy to use, requires significantly less time than the other traditional methods and established plasma sterilization methods, and it is nontoxic. It can be used in the field of sterilization in medical and dental clinics as well as in laboratory settings. (C) 2003 American Institute of Physics.
