Numerical Study of Metachronal Wave-Modulated Locomotion in Magnetic Cilia Carpets. [PDF]
Adv Intell Syst, 2023 Herein, a robust and versatile computational model is introduced that successfully captures the dynamics of metachronal waves in magnetic cilia carpets by integrating granular models into a magnetic–lattice model. The model is also capable of simulating the movement of magnetic soft robots in realistic environments and has the potential to guide the ...

Metachronal waves in the flagellar beating of Volvox and their hydrodynamic origin. [PDF]
J R Soc Interface, 2015 Groups of eukaryotic cilia and flagella are capable of coordinating their beating over large scales, routinely exhibiting collective dynamics in the form of metachronal waves. The origin of this behaviour—possibly influenced by both mechanical interactions and direct biological regulation—is poorly understood, in large part due to a lack of ...

Spontaneous creation of macroscopic flow and metachronal waves in an array of cilia. [PDF]
Biophys J, 2007 Cells or bacteria carrying cilia on their surface show many striking features : alignment of cilia in an array, two-phase asymmetric beating for each cilium, coordination between cilia and existence of metachronal waves with a constant phase difference between two adjacent cilia.

Magnetic cilia carpets with programmable metachronal waves. [PDF]
Nat Commun, 2020 AbstractMetachronal waves commonly exist in natural cilia carpets. These emergent phenomena, which originate from phase differences between neighbouring self-beating cilia, are essential for biological transport processes including locomotion, liquid pumping, feeding, and cell delivery.

A multiscale biophysical model gives quantized metachronal waves in a lattice of beating cilia. [PDF]
Proc Natl Acad Sci U S A, 2022 Significance Understanding the emergence and properties of metachronal waves (MWs) in ciliary arrays is a multiscale problem central to developmental biology, transport phenomena, and nonequilibrium physics, and with potential biomedical applications. For 1D lattices of cilia, we report key mechanisms that lead to the robust emergence of MWs.

Phase-resolved dynamic wavefront imaging of cilia metachronal waves. [PDF]
Quant Imaging Med Surg, 2023 The coordination and the directional order of ciliary metachronal waves are the major factors that determine the effectiveness of mucociliary clearance (MCC). Even though metachronal waves play an essential part in immune response, clinical diagnostic tools and imaging techniques that can reliably and efficiently capture their spatial distribution and ...

Metachronal waves in a chain of rowers with hydrodynamic interactions [PDF]
The European Physical Journal E, 2011 Filaments on the surface of a microorganism such as Paramecium or Ophalina beat highly synchronized and form so-called metachronal waves that travel along the surfaces. In order to study under what principal conditions these waves form, we introduce a chain of beads, called rowers, each periodically driven by an external force on a straight line ...

Emergence of metachronal waves in active microtubule arrays [PDF]
Physical Review Fluids, 2019 The physical mechanism behind the spontaneous formation of metachronal waves in microtubule arrays in a low Reynolds number fluid has been of interest for the past several years, yet is still not well understood. We present a model implementing the hydrodynamic coupling hypothesis from first principles, and use this model to simulate kinesin-driven ...

Emergence of metachronal waves in cilia arrays. [PDF]
Proc Natl Acad Sci U S A, 2013 Propulsion by cilia is a fascinating and universal mechanism in biological organisms to generate fluid motion on the cellular level. Cilia are hair-like organelles, which are found in many different tissues and many uni- and multicellular organisms. Assembled in large fields, cilia beat neither randomly nor completely synchronously—instead they display

Advanced Engineering Materials, Volume 25, Issue 22, November 2023., 2023 A novel multifunctional magnetically actuated micro‐lamellar mechatronic platform for efficient transportation of droplets and small solid objects is reported. The propulsion is realized using a four‐pole rotating magnet, resulting in two modes of object transportation: “pushing” mode for precise positioning and “bouncing” mode for heavier solid ...
