Dynamics of Artificial Helical Microswimmers Under Confinement [PDF]
ASME 2018 16th International Conference on Nanochannels, Microchannels, and Minichannels, 2018 Understanding trajectories of natural and artificial helical swimmers under confinement is important in biology and for controlled swimming in potential medical applications. Swimmers follow helical or straight trajectories depending on whether the helical tail is pushing or pulling the swimmer.

Two-phase flow of gas-liquid mixtures on horizontal helical pipes [PDF]
, 2007 The aim of this study was to investigate hydrodynamic two -phase (namely water and air) fluid flow characteristics in helical pipes of low amplitude and straight pipes of the same internal-diameter and constructional material: the results for the two ...

Fluid flow induced by helical microswimmers in bulk and near walls. [PDF]
Phys Rev Res, 2022 Magnetic nano- and microswimmers provide a powerful platform to study driven colloidal systems in fluidic media and are relevant to futuristic medical technologies requiring precise yet minimally invasive motion control at small scales. Upon the action of a rotating magnetic field, the helical microswimmers rotate and translate, generating flow in the ...

Artificial helical microswimmers with mastigoneme-inspired appendages [PDF]
Biomicrofluidics, 2013 A smooth flagellum moves in the opposite direction of the propagation of flagellar waves. Conversely, a flagellum covered with appendages perpendicular to the main flagellum, called mastigonemes, moves in the same direction as the propagation of flagellar waves.

Velocity Control with Gravity Compensation for Magnetic Helical Microswimmers [PDF]
Advanced Robotics, 2011 Magnetic helical microswimmers, which swim using a method inspired by the propulsion of bacterial flagella, are promising for use as untethered micromanipulators and as medical microrobots. Man-made devices are typically heavier than their fluid environment and consequently sink due to their own weight.

A scalable galvanic approach to microswimmer synthesis [PDF]
, 2021 Microswimmers are small particles capable of converting available energy sources into propulsion owing to their compositional asymmetry and are promising for applications ranging from targeted delivery to enhanced mixing at the microscale.

Modeling and Swimming Property Characterizations of Scaled-Up Helical Microswimmers [PDF]
IEEE/ASME Transactions on Mechatronics, 2014 Micro- and nanorobots capable of controlled propulsion at low Reynolds number are foreseen to change many aspects of medicine by enabling targeted diagnosis and therapy, and minimally invasive surgery. Several kinds of helical swimmers with different heads actuated by a rotating magnetic field have been proposed in prior works.
