Laser ablation synthesis in solution

LASiS is the acronym for Laser Ablation Synthesis in Solution and it is a commonly used method for obtaining colloidal solution of nanoparticles in a variety of solvents.[1][2]

In the LASiS method, nanoparticles are produced during the condensation of a plasma plume formed by the laser ablation of a bulk metal plate dipped in a liquid solution. LASiS is usually considered a top–down physical approach In the past years, laser ablation synthesis in solution (LASiS) emerged as a reliable alternative to traditional chemical reduction methods for obtaining noble metal nanoparticles (NMNp).

LASiS is a ‘‘green’’ technique for the synthesis of stable NMNp in water or in organic solvents, which does not need stabilizing molecules or other chemicals. The so obtained NMNp are highly available for further functionalization or can be used wherever unprotected metal nanoparticles are desired.

Surface functionalization of NMNp can be monitored in real time by UV-visible spectroscopy of the plasmon resonance. However LASiS has some limitations in the size control of NMNp, which can be overcome by ‘‘chemical free’’ laser treatments of NMNp.
