Micromotors from Microfluidics

Abstract

Inspired by the motions of natural objects, attention and efforts have been paid and devoted to fabricate micromotors of spherical, tubular, helical or other shapes for applications in emerging fields including delivery, remediation, and other biomedical applications. Among the proposed methods, the microfluidic technology offers an opportunity to fabricate micromotors with different microstructures. This review presents research progress on micromotors, especially those from microfluidics. The morphologies of the micromotors were firstly outlined. Then, the microfluidic technology used to fabricate different micromotors was discussed. Finally, the applications of these micromotors were briefly introduced, followed by their challenges and future developments.

Keywords: microfluidics; micromotors; microswimmer.
