Controlled particle displacement by hydrodynamic obstacle interaction in non-inertial flows
Partha Kumar Das, Xuchen Liu, Sascha Hilgenfeldt
Systematic deflection of microparticles off of initial streamlines is a fundamental task in microfluidics, aiming at applications including sorting, accumulation, or capture of the…

Principles of hydrodynamic particle manipulation in internal Stokes flow
Xuchen Liu, Partha Kumar Das, Sascha Hilgenfeldt
Manipulation of small-scale particles across streamlines is the elementary task of microfluidic devices. Many such devices operate at very low Reynolds numbers and deflect particle…
