C 2014 American Chemical Society Artificial Micromotors in the Mouse's Stomach: A Step toward in Vivo Use of Synthetic Motors

he development of small-scale syn-thetic motors that convert energy into movement and forces has been a fascinating research area.18 Impressive progressmade over the past decade has led to a variety of powerful microscale motors based on different propulsion mechanisms and design principles. New functionalities and capabilities have been added to these micromotors, leading to advanced micro-scale machines that offer a wide range of important applications. In particular, the movement of man-made micromachines in biological fluids can benefit biomedical fields such as directed drug delivery, diag
