N2 - Titanium dioxide (TiO2) possesses high photocatalytic activity, which can be utilized to power the autonomous motion of microscale objects. This paper presents the first examples of TiO2 micromotors and micropumps. UVinduced TiO2 reversible microfireworks phenomenon was observed and diffusiophoresis has been proposed as a possible mechanism.
