Spermatozoa scattering by a microchannel feature

Abstract

Sperm traverse their microenvironment through viscous fluid by propagating flagellar waves the waveform emerges as a consequence of elastic structure, internal active moments and low Reynolds number fluid dynamics. Engineered microchannels have recently been proposed as a method of sorting and manipulating motile cells the interaction of cells with these artificial environments therefore warrants investigation. A numerical method is presented for large-amplitude elastohydrodynamic interaction of active swimmers with domain features.
