Shape‐Programmable Adaptive Multi‐Material Microswimmers for Biomedical Applications

Advanced Functional Materials
Flagellated microorganisms can swim at low Reynolds numbers and adapt to changes in their environment. Specifically, the flagella can switch their shapes or modes through gene expression.

Chirotactic response of microswimmers in fluids with odd viscosity

Physical Review Research
Odd viscosity is a property of chiral active fluids with broken time-reversal and parity symmetries. We show that the flow of such a fluid around a rotating axisymmetric body is exactly solvable and use this solution to determine the orientational ...

Three-bead steering microswimmers

Physical Review E, 2018
The self-propelled microswimmers have recently attracted considerable attention as model systems for biological cell migration as well as artificial micromachines. A simple and well-studied microswimmer model consists of three identical spherical beads joined by two springs in a linear fashion with active oscillatory forces being applied on the beads ...

Enhanced speed of microswimmers adjacent to a rough surface.

Physical Review E
Increased speed is not only the goal of human sports but also the aim we seek to achieve for artificial microswimmers. Microswimmers driven by various power mechanisms have shown unrivaled advantages in drug delivery and cancer therapy.

Programmable artificial phototactic microswimmer

Nature Nanotechnology, 2016
Phototaxis is commonly observed in motile photosynthetic microorganisms. For example, green algae are capable of swimming towards a light source (positive phototaxis) to receive more energy for photosynthesis, or away from a light source (negative phototaxis) to avoid radiation damage or to hide from predators.
