Special Issue Information

Dear Colleagues,

By virtue of their many unique merits, such as low cost, high throughput, low sample consumption, high flexibility, and precise spatiotemporal control, microscale reactors have attracted increasing attention in the last two decades. The emergence of microscale reactors not only brings new opportunities for engineering of micro-/nanomaterials with more controllable properties but also significantly advances their application potential in diverse fields. To date, passive and active microreactors have been widely employed for process intensification toward advanced chemical engineering, environment science, and biomedical engineering.

This Special Issue of Micromachines aims to gather review papers, short communications, and original research articles that cover all aspects of microscale reactors. Specifically, we invite contributions on, but not limited to, the following topics: 1) microfluidic and nanofluidic reactors for engineering of chemicals and relevant numerical simulation studies; 2) acoustofluidic reactors for chemical engineering, environment science, and biomedical engineering; 3) advanced microreactor fabrication techniques toward rational design of micro-/nanomaterials; 4) design, fabrication, and applications of 3D-printed microreactors; 5) design, fabrication, and applications of paper microreactors; 6) theoretical studies for exploring the relationship between microchannel geometries and mixing intensification.

Abstract
Microrobots can operate in tiny areas that traditional bulk robots cannot reach. The combination of acoustic actuation with microrobots extensively expands the application areas of microrobots due to their desirable miniaturization, flexibility, and biocompatibility features.

Microrobots can operate in tiny areas that traditional bulk robots cannot reach. The combination of acoustic actuation with microrobots extensively expands the application areas of microrobots due to their desirable miniaturization, flexibility, and biocompatibility features. Herein, an overview of the research and development of acoustics-actuated microrobots is provided. We first introduce the currently established manufacturing methods (3D printing and photolithography). Then, according to their different working principles, we divide acoustics-actuated microrobots into three categories including bubble propulsion, sharp-edge propulsion, and in-situ microrotor. Next, we summarize their established applications from targeted drug delivery to microfluidics operation to microsurgery. Finally, we illustrate current challenges and future perspectives to guide research in this field. This work not only gives a comprehensive overview of the latest technology of acoustics-actuated microrobots, but also provides an in-depth understanding of acoustic actuation for inspiring the next generation of advanced robotic devices.
