Hydrodynamic capture and release of a microswimmer by a meniscus corner
Subhasish Guchhait, Harshita Tiwari, Sumesh P. Thampi +1
Biological microswimmers alter their motility in complex corner geometries, facilitating their survival. However, the dynamical features of low-Reynolds-number swimming at corners…
Emergence of run-and-tumble-like swimming in self-propelling artificial swimmers in soft microchannels
Smita S. Sontakke, Aneesha Kajampady, Mohd Suhail Rizvi +1
Biological microswimmers often encounter deformable boundaries in physiological conditions; for instance, the viscoelastic walls of reproductive tract during migration of spermatoz…
Flow fields around active droplets squeezing through tight confinements
Subhasish Guchhait, Smita Sontakke, Shubhadeep Mandal +1
Biological microswimmers, like euglena, deform their body shape to swim through tight confinements having length scales comparable to the microswimmer length scale. Recently, it wa…
Electrotaxis of self-propelling artificial swimmers in microchannels
Carola M. Buness, Avi Rana, Corinna C. Maass +1
Ciliated microswimmers and flagellated bacteria alter their swimming trajectories to follow the direction of an applied electric field exhibiting electrotaxis. Both for matters of…
Confinement induced three-dimensional trajectories of microswimmers in rectangular channels
Byjesh N. Radhakrishnan, Ahana Purushothaman, Ranabir Dey +1
We study the trajectories of a model microorganism inside three-dimensional channels with square and rectangular cross-sections. Using (i) numerical simulations based on lattice-Bo…
Oscillatory rheotaxis of active droplets in microchannels
Ranabir Dey, Carola M. Buness, Babak Vajdi Hokmabad +2
Biological microswimmers are known to navigate upstream of an external flow (positive rheotaxis) in trajectories ranging from linear, spiral to oscillatory. Such rheotaxis stems fr…
