Curved Surfaces Induce Metachronal Motion of Microscopic Magnetic Cilia. [PDF]

ACS Appl Mater Interfaces
Cilia are hair-like organelles present on cell surfaces. They often exhibit a collective wave-like motion that can enhance fluid or particle transportation function, known as metachronal motion.

Viscous dissipation effects on the thermal radiatively induced micropolar fluid using the metachronal wave of cilia in the presence of slip constraints

Advances in Mechanical Engineering
Cilia motion is commonly located in mammalian cells of living organisms which continually grow and feature conspicuously. The ciliary apparatus is associated with cell cycle movement and proliferation, and cilia play a dynamic part in human and animal ...

Influence of Magnetic Field and Slip on Jeffrey Fluid in a Ciliated Symmetric Channel with Metachronal Wave Pattern

Journal of Applied Fluid Mechanics, 2016
The instinct system of cilia motion with magnetic field and slip for Jeffrey fluid model in a symmetric channel is examined. The problem of two-dimensional fluid motion in a symmetric channel with ciliated walls is considered.

Designing metachronal waves of cilia

, 2020
On surfaces with many motile cilia, beats of the individual cilia coordinate to form metachronal waves. We present a theoretical framework that connects the dynamics of an individual cilium to the collective dynamics of a ciliary carpet via systematic coarse-graining.

Robust formation of metachronal waves in directional chains of phase oscillators [PDF]

Physical Review E, 2023
Biological systems can rely on collective formation of a metachronal wave in an ensemble of oscillators for locomotion and for fluid transport. We consider one-dimensional chains of phase oscillators with nearest neighbor interactions, connected in a loop and with rotational symmetry, so each oscillator resembles every other oscillator in the chain ...

Magnetic cilia carpets with programmable metachronal waves [PDF]

Nature Communications, 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.

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 a chain of symmetrically beating filaments [PDF]

Physical Review Research
Recent experiments show that metachronal waves (MCWs) can emerge from a chain of symmetrically beating nematodes aligned at the edge of sessile droplets. Our study, employing a coupled elastohydrodynamic model of active filaments, elucidates that a misalignment caused by a tilt against the bounding wall disrupts the synchronization and generates a ...

Direction selection of metachronal waves in hydrodynamic coordination of cilia [PDF]

Physical Review E
Large arrays of active cilia coordinate their beat cycles into metachronal waves. These waves can travel in different directions with respect to the cilium's beat direction and the resulting direction of fluid propulsion. Hydrodynamic interactions provide a mechanism for the individual cilia to coordinate their beat cycles.

Spontaneous Creation of Macroscopic Flow and Metachronal Waves in an Array of Cilia [PDF]

Biophysical Journal, 2006
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.
