Recent applications of EPR and spin trapping to sonochemical studies of organic liquids and aqueous solutions

In this paper we review some of our recent applications of the EPR spin trapping technique to sonochemical studies which include identification of radicals formed in organic liquids and aqueous mixtures of organic liquids, estimation of temperatures of sonochemical regions in mixtures of deuterated and non-deuterated solvents, and the identification of reactive radical intermediates which may play a role in synergistic cell killing by ultrasound and drugs (sonodynamic interactions).
