Trapping microswimmers in acoustic streaming flow
Xuyang Sun, Wenchang Tan, Yi Man
The acoustofluidic method holds great promise for manipulating microorganisms. When exposed to the steady vortex structures of acoustic streaming flow, these microorganisms exhibit…
Nutrient Transport in Concentration Gradients
Jingyi Liu, Yi Man, Eva Kanso
Sessile ciliates attach to substrates and generate feeding currents to capture passing particulates and dissolved nutrients. Optimal ciliary activity that maximizes nutrient flux a…
Self-diffusiophoretic propulsion of a spheroidal particle in a shear-thinning fluid
Guangpu Zhu, Brandon van Gogh, Lailai Zhu +2
Shear-thinning viscosity is a non-Newtonian behaviour that active particles often encounter in biological fluids such as blood and mucus. The fundamental question of how this ubiqu…
Optimal Feeding of Swimming and Attached Ciliates
Jingyi Liu, Yi Man, John H. Costello +1
Ciliated microorganisms near the base of the aquatic food chain either swim to encounter prey or attach at a substrate and generate feeding currents to capture passing particles. H…
