Light Induced Further Agglomeration of Metal Particles


The observation of an unusual light-induced agglomeration phenomenon that occurs besides the trapping of the gold nanoparticles aggregates (GNAs) has been observed. The observed agglomerate has a 60-100 μm donut-shaped metal microstructure with the rate of formation dependent on the laser power used. In this paper, the forces involved and the mechanism of… (More)
