Physical and chemical diagnostics of cold atmospheric pressure argon plasma jet.

This article presents an experimental investigation of an argon plasma jet. It examines a commercial argon plasma jet device's physical, chemical, and biological impacts, comparing findings against global standards. The study focuses on electrical features ensuring safety for patients and consumers, finding all leakage current values within established standards. Chemical analysis of emitted gases shows no detectable levels of harmful compounds near treated skin. Optical emission spectroscopy reveals bioactive compounds within the plasma jet. UV radiation emission remains within safety thresholds. Hyperspectral imaging shows temporary increases in skin characteristics posttreatment, reverting to baseline over time. Overall, the study demonstrates the safety and potential of the argon plasma jet in skin treatment. [ABSTRACT FROM AUTHOR]
