Simulating wet active polymers by multiparticle collision dynamics

Judit Clopes Llahi et al.

Summary: This study compares the properties of self-propelled and externally actuated active Brownian polymers in a fluid. By implementing a multiparticle collision (MPC) simulation, the conformational and dynamical properties of the active polymers, as well as their scaling behavior with respect to wave number and time dependence, are obtained. The suitability of the implementation is confirmed by comparing the simulation results with theoretical predictions.

Biomedical Micro-/Nanomotors: From Overcoming Biological Barriers to In Vivo Imaging

Changyong Gao et al.

Summary: Self-propelled micro- and nanomotors have great potential in biomedical applications, but challenges such as overcoming biological barriers and in vivo navigation still need to be addressed. With continued attention and innovation, it is believed that they will improve targeted drug delivery efficiency in the future.

Multi-particle collision dynamics with a non-ideal equation of state. I

Arne W. Zantop et al.

Summary: The MPCD method is commonly used in soft matter physics to simulate fluid flow at the micron scale. By modifying collision rules, compressibility of the fluid can be significantly reduced with lower computational costs. Analytical expressions for the equation of state, compressibility, and shear viscosity show good agreement with simulations.

Multi-particle collision dynamics with a non-ideal equation of state. II. Collective dynamics of elongated squirmer rods

Arne W. Zantop et al.

Summary: The article introduces an extended MPCD method with a non-ideal equation of state and viscosity expression, which is demonstrated for flow field simulations of single squirmers and squirmer rods. Results show reduced compressibility in fluids and more pronounced dynamic swarms with higher polar order in simulations using the extended MPCD method. Additionally, a thorough study of the state diagram of squirmer rods moving in the center plane of a Hele-Shaw geometry reveals various states such as disordered state, dynamic swarms, single swarm, and jammed cluster with changing aspect ratio and density.

Motility-induced clustering and meso-scale turbulence in active polar fluids

Vasco M. Worlitzer et al.

Summary: Recent studies on active polar fluids have revealed interesting aspects such as anomalous velocity statistics and clustering phenomena, which cannot be explained by current models. By extending the continuum model, researchers found a long-wavelength instability in addition to the short-wavelength instability, leading to novel dynamics and phenomena related to nucleation and coarsening processes. The interplay between short-range and long-range instabilities results in rich patterns with changing irregularly shaped boundaries, offering a simple explanation for anomalous velocity statistics observed in recent experiments.

Microswimmers learning chemotaxis with genetic algorithms

Benedikt Hartl et al.

Summary: This study introduces a computational model where microswimmers can autonomously navigate in diverse chemical environments and control their shape deformations. Simple neural networks evolve to control the behavior of the microswimmers through the use of an evolutionary algorithm.

Swarming bacteria undergo localized dynamic phase transition to form stress-induced biofilms

Iago Grobas et al.

Summary: Research found that Bacillus subtilis, when exposed to a gradient of kanamycin, activated matrix genes and transitioned to biofilms, with the initial stage of this transition supported by stress-induced multilayer formation. The study suggested a strategy of antibiotic treatment to inhibit the transition from swarms to biofilms by targeting the localized phase transition.

Confinement discerns swarmers from planktonic bacteria

Weijie Chen et al.

Summary: In this study, by confining bacterial movement in circular microwells, it was found that swarming bacteria and planktonic bacteria exhibited different collective motion patterns within a specific size range. The observation of 'rafting behavior' of swarming bacteria upon dilution suggests a potential mechanism for the differences in motion patterns. The experimental design using PDMS microchip disk arrays enabled the observation of bacterial swarming on murine intestinal surface, providing a new method for characterizing bacterial swarming in complex environments.

Active phase separation by turning towards regions of higher density

Jie Zhang et al.

Summary: A new class of behavior in active matter has been discovered, where orientational interactions lead to active phase separation. Experimentally, it was shown that self-propelled Janus colloids exhibit non-reciprocal torques that orient particle motion towards high-density regions, resulting in phase separation into fluid-like clusters.

Increasing the efficiency and maneuverability of one-hinge swimmer

Priyanka Choudhary et al.

Summary: This study explores a two-dimensional one-hinge swimmer with non-uniform bending rigidity distribution along its arms, showing higher swimming speed and efficiency. The research also demonstrates the maneuverability of the swimmer with asymmetrical bending rigidity, leading to curved paths, and the control of angular velocity, curvature, and direction of rotation by adjusting the relative bending rigidity of the arms.

Cluster and conquer: the morphodynamics of invasion of a compliant substrate by active rods

Mohammad Imaran et al.

Summary: Research has shown that clustering of active particles is crucial for understanding the morphodynamics of cell colonisation in a passive compliant medium. The furrow networks created by active particles have a fractal-like structure, with the dimension varying systematically with substrate stiffness. Clustering of active particles allows colonies to spread faster than isolated particles.

3-D swimming microdrone powered by acoustic bubbles

Fang-Wei Liu et al.

Summary: This article introduces a bubble-powered swimming microdrone that can navigate in a controlled manner in three-dimensional space, using microtubes embedded and three-dimensionally aligned inside the drone body with bubble of three different lengths. The bubbles can generate on-demand 3-D propulsion through microstreaming, and the drone is designed with non-uniform mass distribution for highly stable maneuverability.
