Abstract: The talk will review the work done by the group of kinetics of nanosecond discharges of Laboratory of Plasma Physics in the direction of studying of plasma parameters and optimizing plasma chemistry. Special attention will be payed to techniques related to optics, plasma action on cell morphology and measuring of ROS produced by plasma. The capabilities of the phase imaging technique, Quadriwave Lateral Shearing Interferometry (QLSI) as a diagnostic for the plasma action on living cells will be discussed. A novel approach to calibration of ratio of two-photon Xe/O cross-sections for two-photon absorption fluorescence (TALIF) of atomic oxygen will be presented. Bio: Svetlana Starikovskaia received the Ph.D. in Plasma Physics from Moscow Institute of Physics and Technology (MIPT) in 1993, Dr.Sc. degree from Joint Institute of High Temperatures Russian Academy of Sciences in Moscow State University in 2000 and degree of Professor from MIPT in 2006. She is currently a CNRS Leading Scientific Researcher in Laboratory of Plasma Physics (LPP) and Professor at Ecole Polytechnique, Palaiseau, France. Her scientific interest involves molecular energy transfer, non-equilibrium plasma, plasma-assisted combustion, shock waves and chemical kinetics, plasma conversion of CO2, plasma-living cells interaction.
