“…Ultrasound Propelled LM Robots : Control and actuation of objects by means of ultrasound have attracted increasingly attention during the past years. The tiny agents (droplets) suspended in solution are propelled by the acoustic radiation forces, which generate both the primary radiation force (responsible for the migration of the agents) and the secondary radiation force (responsible for the repulsion and attraction between the agents) . Ultrasound field triggered actuation can be adaptable for various kind of micro‐/nanoagents such as nanowires and nanospheres, and it shows the merits of noninvasive, on‐demand motion control and long service time.…”

Motivated by the increasing demand of wearable and soft electronics, liquid metal (LM)‐based microfluidics has been subjected to tremendous development in the past decade, especially in electronics, robotics, and related fields, due to the unique advantages of LMs that combines the conductivity and deformability all‐in‐one. LMs can be integrated as the core component into microfluidic systems in the form of either droplets/marbles or composites embedded by polymer materials with isotropic and anisotropic distribution. The LM microfluidic systems are found to have broad applications in deformable antennas, soft diodes, biomedical sensing chips, transient circuits, mechanically adaptive materials, etc. Herein, the recent progress in the development of LM‐based microfluidics and their potential applications are summarized. The current challenges toward industrial applications and future research orientation of this field are also summarized and discussed.

“…In order to circumvent these hindrances, another propulsion, i.e., fuel‐free actuation, shows considerable promise for remote navigation in complex biological fluids and hard‐to‐access locations via conventional methods. It is mainly based on the exertion of the external energy field to drive the micro/nanomachines . With the demands on precisely controlled motion without fuels in biomedical applications, a variety of external fields is used to propel the micro/nanomachines nowadays.…”

“…Generally, micro/nanomachines get power from chemical and physical reactions. Specifically, they convert different energy sources or mechanical work into driving forces either through consuming fuel from surrounding media or by harnessing external energy sources such as electrical, light, magnetic, ultrasound fields, and these combinations, as well as living microorganisms . Owing to these great technological advances, past years have witnessed a multitude of innovations in the design, fabrication, and application of artificial inorganic micro/nanomachines with various micro/nanostructures, ranging from 1D wire structures to 1D tubular structures to Janus spherical structures to complex 3D structures.…”

Micro/nanomachines have attracted tremendous interest in chemo/bioanalytical science and environmental remediation due to the synergistic effect of unique motion characteristics and the inherited physicochemical properties from micro/nanomaterials. Past decade has witnessed great progresses on a wide array of micro/nanomachines with diverse functionalities for specific sensing and removal applications. The development of designed materials and structures, the exploration of new propulsion mechanism, and the realization of versatile functionalization are employed for potential applications. In this review, the recent advances in the exploration of functionalized micro/nanomachines are summarized, with special emphasis on the functionalization of micro/nanomachines and their corresponding sensing and removal capability. Possible challenges facing micro/nanomachines in sensing and removal application are discussed, accompanied with the extrapolated perspectives for the future focus.

“…In order to achieve precise treatment of cancer, it is required that the nanoparticles are distributed at a reasonable time and space at the target site, so they can be efficiently taken up and released by the cells, which requires a reasonable construction of the delivery system to avoid multiple obstacles to transport to the tumor site. Self-propelled micro/ nanomotors, an emerging and powerful agent that is capable for effectively converting diverse energy sources into driving forces and autonomous movement [12][13][14][15][16][17][18][19][20], have gained considerable attention in the field of tumor diagnostics and treatment. Self-propelled micro/nanomotors not only inherit the excellent properties of micro/nanomaterials, such as high surface area and activity, but also demonstrate the distinct feature of autonomous motion capacity, which both results in highly efficient bioseparation and in precise delivery of imaging agents or drugs to the subcellular target in tumors [21][22][23][24][25][26][27][28][29][30].…”
