Elastohydrodynamic coupling enhances flow generation by coordinated ciliary beating
Shota Nakano, Shinji Deguchi, Daiki Matsunaga
Ciliary arrays pump fluid at low Reynolds number through non-reciprocal beating and phase coordination between neighbouring cilia. Previous studies have demonstrated that antiplect…
Tuning microswimmer motility by liposome encapsulation: swimming and cargo transport of Chlamydomonas-encapsulating liposome
Koichiro Akiyama, Sota Hamaguchi, Hiromasa Shiraiwa +4
Inspired by biology's use of vesicles for targeted transport, many studies have propelled liposomes with active matter, creating synthetic systems that can be viewed as microscale…
Modeling bacterial flow field with regularized singularities
Yaochen Yang, Daiki Matsunaga, Da Wei +1
The flow field generated by a swimming bacterium serves as a fundamental building block for understanding hydrodynamic interactions between bacteria. Although the flow field genera…
Cell-induced wrinkling patterns on soft substrates
Aleksandra Ardaševa, Varun Venkatesh, Daiki Matsunaga +2
Cells exert traction forces on compliant substrates and can induce surface instabilities that appear as characteristic wrinkling patterns. Here, we develop a mechanical description…
Optimal Undulatory Swimming with Constrained Deformation and Actuation Intervals
Fumiya Tokoro, Hideki Takayama, Shinji Deguchi +2
In nature, many unicellular organisms are able to swim with the help of beating filaments, where local energy input leads to cooperative undulatory beating motion. Here, we investi…
