Abstract
Formation of laser plume by laser-tissue interaction means an inhomogeneous, pluriphasic and dynamic multicomponent system of biological material and induced modifications. While IR_laser applications often simulate processes of thermal food preservation, UV-lasers favor formation of aromatic organic compounds as VOC. Along with traces of PAH, nitriles and O-/N-containing heterocyclic compounds two classes of dialkyldiketopyrroli(di)nes are special formed VOC as laser solvents. Inhalable particles or partially dried and modified biomass contain - along with infectious particles - a lot of temperature degradation products. Ames tests and Comet-assays gave hint to some mutagenic activities present in laser smoke.
