Abstract
Micro- and nanomotors (MNMs) are micro/nanoparticles that can perform autonomous motion in complex fluids driven by different power sources. They have been attracting increasing attention due to their great potential in a variety of applications ranging from environmental science to biomedical engineering. Over the past decades, this field has evolved rapidly, with many significant innovations contributed by global researchers. In this review, we first briefly overview the methods used to propel motors and then present the main strategies used to design proper MNMs. Next, we highlight recent fascinating applications of MNMs in two examplary fields, water remediation and biomedical microrobots, and conclude this review with a brief discussion of challenges in the field.
Highlights
We presented an integral profile of micro- and nanomotors (MNMs) progress in recent years
Light, we presented integral of MNMs in recent magnetic and acoustic field
MNMs for environmental remediation and biomedihave been introduced to impressive provide a guidance in designing high-performance
Summary
MNMs are small autonomous devices capable of performing complex tasks while being self-propelled in fluids [2,3,4,5,6,7,8,9,10,11,12,13] They can convert energy into motion by consuming fuels in solutions or by absorbing power from external sources such as ultrasound [14], light, thermal fields [15], magnetic fields [16], etc., and are able to transport mass to specific destinations at the micro/nano scale [6].
