Geometry and surface morphology effects for Catalytic Nano-Mobile Robot

In this paper, we develop the Catalytic Nano-mobile Robot (CNMR) by Focus Ion Beam (FIB), which can swim in hydrogen peroxide solution as a novel type of nano machine. And then an effective and stable manipulation method in sub micrometer scale and liquid environment is shown to operate the fabricated nano-mobile robot. Following up the manipulation method, we get the movement of the nano-mobile robot. And then the effects of geometry and surface morphology of CNMR on its movement are evaluated. The evaluations show that the geometry of CNMR can have effect on the trajectory greatly, and the surface morphology can also influence the direction of the oxygen bubbles propulsion force.
