Abstract:

We investigated the use of the fluorescent dye 2,7-dichlorodihydrofluorescein diacetate (H2DCFDA) to detect peroxynitrites in air plasmas activated water (PAW) by transient spark discharge. The selectivity of the dye was investigated with the respect to peroxynitrites detection by using scavengers of reactive oxygen and nitrogen species (ROS and RNS) and dyes selective for others ROS/RNS. The aim of this study is to distinguish the part of the fluorescent signal that is due to the peroxynitrites presence in PAW.
