Medical applications of cold atmospheric plasma: state of the science

Cold atmospheric plasmas (CAP) have been used in multiple medical fields and have become a promising medical technology. CAP-generating devices are safe and easy to operate and can now be manufactured at a low cost due to advancements in electronics and microchips. A primary application of CAP is as a broad-spectrum antimicrobial technology. With the high incidence of infections caused by drug-resistant microorganisms, a non-antibiotic based treatment modality such as CAP holds great therapeutic promise, particularly in the wound care field. In addition to its antimicrobial properties, CAP treatment enhances wound healing by increasing cutaneous microcirculation, monocyte stimulation, and keratinocyte proliferation. CAP has been used by dentists for disinfection of teeth, enhancing gingival fibroblast activity, and even teeth whitening. CAP can combat tumour growth by increasing the efficacy of antitumour therapeutic agents, reactivating apoptotic pathways, or down-regulating growth-related gene sites. Most of the health-care related research on CAP has occurred in the past 15 years; the field is relatively young and needs additional research, as well as confirmation of the existing supporting literature. The purpose of this report is to provide the reader with an overview of the therapeutic application of the cold plasma technology.
