Abstract
Micro/Nano robots have shown enormous potential for diverse biomedical applications, such as targeted delivery, in vivo biosensing, minimally invasive surgery andcell manipulation through extending their area of operation to various previously inaccessible locations. The motion of these small-scale robots can be eitherself–propelled or remotely controlled by some external power sources. However, in order to use them for biomedical applications, optimization of biocompatiblepropulsion and precise controllability are highly desirable. In this article, the recent progress about the biocompatible propulsion (e.g. self-propulsion, externalstimuli based propulsion and bio-hybrid propulsion) techniques for these micro/nano robotic devices are summarized along with their applications, with a specialfocus on the advantages and disadvantages of different propulsion techniques. The current challenges and future perspectives of these small-scale devices arediscussed in thefinal section.
