We demonstrated a selective production of dinitrogen pentoxide (N₂O₅) from air using atmospheric pressure plasma technology. This device enables us to investigate roles of N₂O₅ in plasma-induced chemical effects. Solutions of tyrosine, an amino acid, were treated by various plasma effluent gases (e.g., N₂O₅-rich, N₂O₅+O₃) and the products were analyzed. The results and a chemical reaction model will be shown and discussed.
