Summary: Inspired by the desire to imitate nature, micro- and nanorobots have gained increasing interest. The use of organic components, such as polymers, can address the biocompatibility and biodegradability issues of inorganic-based microrobots. Additionally, combining self-powered micro- and nanorobots with the properties of macromolecules is an important area of research.

Summary: We proposed a method to modulate the drifting motion of overdamped circle swimmers in steady fluid flows by static sinusoidal potentials, and quantified the drift velocity as a function of potential strength and wavelength with and without diffusional motion. The results show that drift velocity is essentially quantized without diffusion but has a continuous range with noise, and different regimes can be observed based on the dimensionless potential wave number in the drift velocity diagram. This method can help differentiate biological and artificial circle swimmers based on their dynamical properties.

Summary: This study introduces motors that utilize surface polymerization to achieve locomotion, mimicking the propulsion mechanism of microorganisms. By using mesoporous Janus particles, these motors exhibit enhanced Brownian motion and have the potential for various applications. Swarming behavior is observed in motors coated with atom-transfer radical polymerization initiators, while high-density Janus motors lose their ability to enhance Brownian motion.

Summary: Inspired by natural mobile microorganisms, researchers have developed micro/nanomotors (MNMs) that can autonomously move and have made tremendous progress in various biomedical applications. However, controversy and challenges still exist in propulsion mechanisms and motion manipulation of MNMs. Recently, diverse MNMs with different propulsion strategies, morphologies, sizes, porosities, and chemical structures have been fabricated and utilized for various purposes.

Summary: The popular principle of designing chemical micro-machines based on asymmetric chemical reactions like catalytic decomposition of H2O2 may not be sufficient in powering the micromotors into self-propulsion. Surface morphology plays a critical role in enabling/disabling the performance of catalytic caps on chemical micromotors. This study offers a refreshed perspective on understanding how chemistry powers nano- and microscopic objects by emphasizing the importance of an electrochemical mechanism over nonelectrochemical pathways in self-propulsion.

Summary: One key method for designing bioinspired machines is transferring concepts from nature to man-made structures by integrating biomolecules into artificial mechanical systems, allowing the conversion of molecular information into macroscopic action. Hybrid bioelectrochemical swimmers can convert chiral information into enantiospecific macroscopic trajectories, with potential biomedical applications and food quality testing.

Summary: Due to the challenges posed by the complex environment of the intestine, it is difficult to accurately diagnose intestinal cancer using traditional methods. This highlights the need for new body-friendly diagnostic methods. Micro- and nanomotors have the potential for biomedical applications in restricted environments, but recycling has been a constraint in collecting biological tissues for diagnosis. In this study, a multi-functional medical ship (MFMS) is proposed as an intelligent and controllable transportation platform that can be rapidly driven by a magnetic field. It provides a solution for transportation and recovery of micro- and nanomotors and cargoes, as well as the controlled release of magnetic nanoparticles (MNPs) and collection of intestinal tissues. This MFMS is expected to be a new tool for medical tasks within the digestive system.

Summary: Scientists have designed synthetic molecular motors inspired by nanomotors in nature to drive the motion of microscale objects through cooperative reorganization. In this study, topological vortices are imprinted in monolayers of azobenzene molecules, which induce the collective motion of liquid crystal molecules and the spatiotemporal evolutions of nematic disclination networks. The collective transport and reconfiguration of colloidal assemblies can be controlled by manipulating the irradiated polarization, opening opportunities for programmable colloidal machines and smart composite materials.

Summary: This study proposes a simple method to detect the physical features of nanoswimmers by observing their effect on the motion of larger particles. By modeling the swimmers as hydrodynamic force dipoles, the study establishes direct and easy-to-calibrate relations between the observable power spectrum and diffusivity of the tracers, and the dynamic characteristics of the swimmers.

Summary: By using the R-D process with a rotary furnace, the problem of uneven distribution of Ca in the reaction vessel was solved, leading to a reduction in the formation of Sm-Ca-Fe lumps and coarse Sm2Fe17 particles. As a result, Sm2Fe17N3 powders with higher coercivity could be obtained by the R-D process.
