Asymmetric nanoscale objects – metallic nanorods, photocatalysts, enzymes, and even individual catalyst molecules – have been shown to generate force and “swim” when catalyzing chemical reactions.  Some of these objects can also be propelled in fluids by using light or ultrasound, and their modes of propulsion can be combined to achieve more complex functionality.  Recent examples include swimmers that can move up- or downstream in flows, climb stairs, and navigate through fluids in three dimensions.  This talk will describe some recent advances in the design of  these swimmers as well as our progress in addressing fundamental questions about the scaling of forces and the mechanisms of propulsion on the nanoscale.<br/>
