Abstract
BETTERA MARCAT, M.A; BANCHIO, A.J and MARCONI, V.I. Microconfined spermatic cells: wall interaction. An. AFA [online]. 2018, vol.29, n.4, pp.111-115. ISSN 0327-358X.
In order to reproduce numerically confined human sperm dynamics into micro-devices, in this work we improve previous models of such systems. We model the spermatic cells motility using a 2D Langevin dynamics and we propose a wall interaction generating a torque to the microswimmers that aligns its trajectories parallel to the walls, in closer connection with experimental observations. The effect of this interaction in the simulated cell distribution close to the walls was analized and it reduces an overestimation of the wall acummulation obtained with previous and simpler models. A nice agreement between the obtained distributions of cell close to the walls and previous experiments is obtained.
