Biohybrid Microswimmers Against Bacterial Infections [PDF]
Acta Biomaterialia, 2021 AbstractBiohybrid microswimmers exploit the natural abilities of motile microorganisms e.g. in releasing cargo on-demand with high spatial and temporal control. However, using such engineered swarms to deliver antibiotics addressing bacterial infections has not yet been realized.

Optimal turbulent transport in microswimmer suspensions [PDF]
Physical Review Fluids, 2022 Microswimmer suspensions self-organize into complex spatio-temporal flow patterns, including vortex lattices and mesoscale turbulence. Here we explore the consequences for the motion of passive tracers, based on a continuum model for the microswimmer ...

Orientational dynamics and rheology of active suspensions in weakly viscoelastic flows
Communications Physics, 2023 Microswimmer suspensions in Newtonian fluids exhibit unusual macroscale properties, such as a superfluidic behavior, which can be harnessed to perform work at microscopic scales.

Bio-inspired in silico microswimmer: Run and tumble kinematics
The Physics of Fluids, 2023 We present an in silico microswimmer motivated by peritrichous bacteria, E. coli, which can run and tumble by spinning their flagellar motors counterclockwise (CCW) or clockwise (CW).

Wall-curvature driven dynamics of a microswimmer [PDF]
Physical Review Fluids, 2021 Microorganisms navigate through fluid, often confined by complex environments, to survive and sustain life. Inspired by this fact, we consider a model system and seek to understand the wall curvature driven dynamics of a squirmer, a mathematical model ...

Towards an analytical description of active microswimmers in clean and in surfactant-covered drops [PDF]
, 2020 Geometric confinements are frequently encountered in the biological world and strongly affect the stability, topology, and transport properties of active suspensions in viscous flow.

MRI driven magnetic microswimmers [PDF]
Biomedical Microdevices, 2011 Capsule endoscopy is a promising technique for diagnosing diseases in the digestive system. Here we design and characterize a miniature swimming mechanism that uses the magnetic fields of the MRI for both propulsion and wireless powering of the capsule. Our method uses both the static and the radio frequency (RF) magnetic fields inherently available in
