Abstract

The recent tremendous progress in understanding physical plasma phenomena, together with the development of new plasma sources, has put a growing focus on the application of nonthermal plasmas in the biomedical domain. Among several novel applications, the inactivation of bacteria by nonthermal plasmas (so-called plasma sterilization) is particularly interesting. This introductory review provides a summary of the current status of this emerging research field. In addition to the inactivation of bacteria on nonliving surfaces, this review also focuses on the sterilization of living surfaces, such as animal and human tissues. Clearly, nonthermal plasmas have undoubtedly great potential as a novel method for low-temperature sterilization.
