Cold atmospheric pressure plasma (CAPP) is used in medicine, agriculture, and food processing for its antimicrobial properties, producing reactive oxygen and nitrogen species (RONS). While it can effectively treat diseases and enhances seed germination, CAPP can also cause side effects like lipid peroxidation and DNA damage. This study tries to understand these plasma interactions is essential to mitigate potential side effects in various applications, including the detection of nitrites and nitrates in treated water using Bartovation test strips.
