Laser ablation synthesis in solution
Laser ablation synthesis in solution (LASiS) is a commonly used method for obtaining colloidal solution of nanoparticles in a variety of solvents.[1][2] Nanoparticles (NPs,), are useful in chemistry, engineering and biochemistry due to their large surface-to-volume ratio that causes them to have unique physical properties[3]. LASiS is considered a "green" method due to its lack of use for toxic chemical precursors to synthesize nanoparticles.[3][4][5]
In the LASiS method, nanoparticles are produced by a laser beam hitting a solid target in a liquid and during the condensation of a the plasma plume, the nanoparticles are formed. Since the ablation is occurring in a liquid, versus air/vacuum/gas/, the environment allows for plume expansion, cooling and condensation with a higher temperature, pressure and density to create a plume with stronger confinement.
LASiS is a 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 laser treatments of NMNp.
