We have developed a new fabrication method for a ring structure of assembled nanoparticles on a gold surface by the use of continuous Nd:YAG laser light. A micronanobubble on a gold surface, created by laser local heating, acts as a template for the formation of the ring structure. Both Marangoni convection flow and capillary flow around the micronanobubble are responsible for the driving force to assemble nanoparticles such as CdSe Q-dots into the ring structure from the solution. Because a… Expand
Continuous Nanoparticle Assembly by a Modulated Photo-Induced Microbubble for Fabrication of Micrometric Conductive Patterns.
TLDR
It is shown that continuous patterns can be formed by preventing the microbubble from being pinned to the deposited material by modulating the laser so that the construction and destruction of the micro bubble are controlled. Expand

Simultaneous Formation and Spatial Patterning of ZnO on ITO Surfaces by Local Laser-Induced Generation of Microbubbles in Aqueous Solutions of [Zn(NH3)4]2.
TLDR
The Marangoni convection generated in the vicinity of the microbubbles resulted in a rapid concentration/accumulation of [Zn(NH3)4]2+ around the micro bubbles, which led to the formation of ZnO at the solid-bubble-solution three-phase contact line around the bubbles and thus afforded ZnNO nanocrystals on the ITO surface upon local heating with a laser.
