Abstract

A lot of work has been done in the area of laser sterilization using UV lasers whereas this area is not much explored using an IR laser. In this study the cells were catapulted from glass or oxidized silicon substrates by a nanosecond IR CO₂ laser. Removal of cells and bacteria was achieved under the micron thick liquid layer pre-deposited on the substrates and lifted off together with biological species at laser fluences exceeding the corresponding boiling thresholds for the liquids used. Catapulting with front-side laser illumination is studied
