Enhanced ion tolerance of electrokinetic locomotion in polyelectrolyte-coated microswimmer
Nature Communications, 2019 Electrophoretic microswimmers aren’t well suited to function in vivo because electric-field screening reduces their speed in higher ionic-strength solutions.

Synthesis and characterization of bismuth magnetic microswimmer for degradation of polystyrene microplastics / Khairunnisa Khairudin [PDF]
, 2023 Microplastics ranged from 1 μm to 5 mm but the occurrence of smaller microplastics (micron-sized) has become a major concern due to their larger surface area, which can accumulate and transport other contaminants such as heavy metals and chemical ...

Modeling a spheroidal microswimmer and cooperative swimming in thin films [PDF]
, 2016 We propose a hydrodynamic model for a spheroidal microswimmer with two tangential surface velocity modes. This model is analytically solvable and reduces to Lighthill's and Blake's spherical squirmer model in the limit of equal major and minor semi-axes.

Collision of microswimmers in a viscous fluid
Physical Review E, 2013 We investigate the effects of boundary conditions on the surface of self-propelled spherical swimmers moving in a viscous fluid with a low Reynolds number. We first show that collisions between the swimmers are impossible under the commonly used no-slip conditions.

Stability of a Dumbbell Micro-Swimmer
Micromachines, 2019 A squirmer model achieves propulsion by generating surface squirming velocities. This model has been used to analyze the movement of micro-swimmers, such as microorganisms and Janus particles.

Viscotaxis: microswimmer navigation in viscosity gradients [PDF]
, 2018 The survival of many microorganisms, like Leptospira or Spiroplasma bacteria, can depend on their ability to navigate towards regions of favorable viscosity.

Motion of microswimmers in cylindrical microchannels
Soft MatterMicroswimmers in confinement slow down, and can exert pulling or pushing forces in particular at the end of a closed channel. Simulations and approximate theoretical calculation for the squirmer model are employed to predict this behavior.
