Motion Manipulation of Micro- and Nanomotors

Motion Manipulation of Micro- and Nanomotors
Daniela A. Wilson, Fei Peng, Yingfeng Tu
Inspired by the self-migration of microorganisms in nature, artificial micro- and nanomotors can mimic this fantastic behavior by converting chemical fuel or external energy into mechanical motion. These self-propelled micro- and nanomotors, designed either by top-down or bottom-up approaches, are able to achieve different applications, such as environmental remediation, sensing, cargo/sperm transportation, drug delivery, and even precision micro-/nanosurgery. For these various applications, especially biomedical applications, regulating on-demand the motion of micro- and nanomotors is quite essential. However, it remains a continuing challenge to increase the controllability over motors themselves. Here, we will discuss the recent advancements regarding the motion manipulation of micro- and nanomotors by different approaches. On-demand regulation of the motion of artificial micro- and nanomotors is essential for diverse applications. The recent progress made during the last decade to manipulate the motional behavior of micro- and nanomotors by various approaches (such as light, magnetic fields, ultrasound, electric fields, temperature, pH, chemotaxis, and the addition of chemicals) is discussed.
