OES Spectroscopic Measurements of Temperatures and Densities of Charged Particles in Micro-Air Plasma for Gene Transfection

摘要

The aim was to characterize by optical emission spectroscopy measurements our mu-air plasma discharge successfully used for gene transfection. We estimated rotational Trot and electron T. temperatures, and densities of charged particles. In this study, we aimed to experimentally characterize a u-air plasma discharge using optical emission spectroscopy (OES) measurments. This mu-air plasma has been successfully used for gene transfection. We estimated rotational temperatures (T_rot) and electron temperatures (T ) as well as densities of charged particles (electrons and N2+ molecular nitrogen ions). Figure 1 displays the coronal discharge setup generated from the tip of a pulsed high-voltage microtube placed 2 mm in front of a Petri dish containing deionized water and placed over a grounded copper plate. Table 1 summarizes temperatures and densities for several z positions in the interelectrode space.
