Nanometer sized particles can show size dependent physical and chemical properties. Hence,
preparation of size-controlled metal nanoparticles in a solution is one of the important subjects in
chemistry and physics of nano-scale materials. A considerable number of efforts have been directed for
developing methods of their preparation such as chemical reduction of a metal salt in a micelle or a
reversed micelle. On the analogy of the laser ablation for preparing gas-phase clusters, a laser ablation
method for preparation of metal nanoparticles in a liquid has also been developed by many researchers.
Recent development of laser ablation in a solution for the nanoparticle production is overviewed.
Mechanism of nanoparticles formation, size-reduction and relevant physical processes are described.
