Modelling Motility: The Mathematics of Spermatozoa

Frontiers in Cell and Developmental Biology, 2021
In one of the first examples of how mechanics can inform axonemal mechanism, Machin's study in the 1950s highlighted that observations of sperm motility cannot be explained by molecular motors in the cell membrane, but would instead require motors ...

Interactions Between Active Matters and Endogenous Fields

Advanced Materials, EarlyView.
This review synthesizes endogenous field information and computational methods in contexts such as cancer, wounds, and biofilms. It organizes NAMs and AAMs by sensing, transmitting, and executing functions, compares their limitations, and from these contrasts proposes design strategies for next‐generation AAMs, offering perspectives to foster ...

Pea broth enhances the biocontrol efficacy of Lysobacter capsici AZ78 by triggering cell motility associated with biogenesis of type IV pilus

Frontiers in Microbiology, 2016
Bacterial cells can display different types of motility, due to the presence of external appendages such as flagella and type IV pili. To date, little information on the mechanisms involved in the motility of the Lysobacter species has been available ...

Soft Robotic Engines with Non‐Reciprocal Motion by Physical Intelligence

Advanced Materials, EarlyView.
Movement is vital, and it requires breaking symmetry. This study introduces a hydrogel engine that achieves non‐reciprocal motion through kinetic asymmetry in repeated actuation cycles. This approach for breaststroke‐swimming‐like motion is embedded inside the material and establishes a new paradigm of physical intelligence for soft robotics.

Resistance of Oil‐Infused PDMS with Different Macroporosities Against Bacterial Attachment

Advanced Materials Interfaces, EarlyView.
In this study, a series of environmentally benign, nonfluorinated liquid paraffin‐infused porous PDMS networks with varying porosities is created. By introducing different homogenous and heterogenous bulk structures and varying interfacial roughness by sugar and salt templating, the role of porosity and oil availability on the resistance against ...

Multimodal Actuation and Environment Adaptive Strategies of Bio‐Inspired Micro/Nanorobots in Precision Medicine

Advanced Robotics Research, EarlyView.
An introduction for multidrive and environment‐adaptive micro/nanorobotics: design and fabrication strategies, intelligent actuation, and their applications. Various intelligent actuation approaches—magnetic, acoustic, optical, chemical, and biological—can be synergistically designed to enhance flexibility and adaptive behavior for precision medicine ...

Difference in the chemotaxis between monotrichous and peritrichous bacteria clarified by a numerical simulation and observation

Journal of Biomechanical Science and Engineering, 2022
We investigate difference in the chemotactic behavior between peritrichous bacteria (Salmonella typhimurium SJW1103) and monotrichous bacteria (Vibrio alginolyticus YM4).
