Our research group has successfully developed a device that can synthesize dinitrogen pentoxide (N₂O₅) on-site using atmospheric pressure air plasma. Our experiments have revealed that N₂O₅ possesses potent antifungal, antiviral, and plant immunomodulatory properties. Despite these findings, the mechanisms underlying these effects remain poorly understood. Additionally, there is limited knowledge of the reactions between N₂O₅ and amino acids or proteins, which are fundamental components of living organisms. To address this, we conducted a study that focused on analyzing the derivatives of 18 amino acids resulting from their reaction with N₂O₅, using LC-PDA-MS.
