摘要: The guidance of human sperm cells under confinement in quasi-2D microchambers is investigated using a purely physical method to control their distribution. Transport property measurements and simulations are performed with diluted populations, for which effects geometrical concentration studied detail. In particular, trapping transition at convex angular wall features identified analyzed. We also show that highly efficient microratchets can be fabricated by curved asymmetric obstacles take advantage the spermatozoa specific swimming strategy.
