Plasmas, lasers and nanostructures

Pulsed Laser Ablation in Liquids (PLAL) from the experimental point of view is a relatively simple process to produce nanoparticles (NPs) and nanostructures in a “clean” way without dangerous reactants or undesired contaminants, requiring no extreme conditions of the environment synthesis. Several promising advantages, such as environmental sustainability, easy set-up, long stability of the produced NPs, the possibility of further functionalization and the comparatively low cost have led to the growing interest in the NPs production by PLAL and that is why the research in this field is rapidly developing. However much still needs to be clarified, in particular the formation mechanisms of NPs. Many phenomena such as laser-matter interaction, plasma chemistry and dynamics, cavitation bubble, particle nucleation should be taken into account.

These kind of “naked” NPs can be successfully employed in a wide range of application fields taking advantages of their different surface reactivity (if compared to the surface of the coated-NPs produced by chemical methods).
