“…A novel method that draws inspiration from fish biomechanics has been presented by Wang et al [ 59 ] outlining a magnetic microrobot designed specifically for the effective transportation of microparticles along liquid surfaces. This 850 μm × 500 μm × 200 μm microrobot is cleverly designed as a monolithic sheet structure with inherent magnetic properties, in contrast to its aquatic counterparts that are propelled by flexible caudal fins.…”

The emergence of micro/nanorobotics stands poised to revolutionize various biomedical applications, given its potential to offer precision, reduced invasiveness, and enhanced functionality. In the face of such potential, understanding the mechanisms that drive these tiny robots, especially their actuation techniques, becomes critical. Although there is a surge in research dedicated to micro/nanorobotics, there exists a gap in consolidating the diverse actuation strategies and their suitability for biomedical applications. This comprehensive review seeks to bridge this gap by providing an in‐depth evaluation of the current actuation techniques employed by micro/nanorobots, particularly emphasizing their relevance and potential for clinical translation. The discussion starts by elucidating the different actuation strategies, ranging from magnetic, electric, acoustic, light‐based, to chemical and biological mechanisms. Then, various examples and meticulous assessment of each technique are offered, spotlighting their respective merits and limitations within a biomedical context. This review illuminates the transformative capabilities of these actuation methods in medicine. It not only highlights the progress made in this burgeoning field but also underscores the areas that require further exploration and development.

The transient and elusive intermediate states are the keys in self‐assembly processes, which are common phenomena shaping the structure, properties, and functionalities of assembled materials across many scientific domains. However, the understanding about the intermediate states of self‐assembly process is always challenging and limited. In this review, we focus on these states by combining theoretical and experimental approaches. By examining a wide variety of self‐assembly systems that span from biological to metal–organic nanostructures, this review uncovers the wealth of intermediate states of self‐assembled materials. In addition to combining the current knowledge, it will identify challenges and provide a new insight into the opportunities for future research.

“…The diverse plants and animals in nature exhibit unique characteristics and adaptability against complicated and inconsistent environments. Inspired by the unique features of plants and animals in nature, researchers have developed stimuli responsive actuating soft micro-robots like fish, 1,2 snakes, 3,4 mudskippers, 5 caterpillars, 6 and water striders. 7,8 Compared to conventional rigid actuators, soft actuators are flexible, lightweight, adaptable, bio-compatible, and have mechanically strong.…”
