Abstract

We report a method for manipulating sequential single DNA strands by using a micronanobubble formed by local laser heating on a Au surface. DNA strands near the laser focal point were quickly pulled toward the focal point. This DNA pull-in phenomenon can be explained by Marangoni convection due to a micronanobubble generated by laser heating on the Au surface. The thickness of Au film plays a crucial role for absorbing the IR laser light.
