2005-9-30 · Microfluidic channels allow for non-turbulent bathing of gametes with fresh media throughout insemination and co-incubation. Sperm–oocyte interactions occur in an active environment rather than the static conditions present in a culture dish or droplet. In addition via laminar flow sperm can be predictably delivered to each oocyte within
2004-2-1 · On the other hand the proposed approach is readily adaptable to fabrication of three-dimensional microfluidic channel networks. In addition an easy fabrication of gas-porous silicon-oxide membranes from PDMS was demonstrated leading to potential applications for outgassing of microfluidic channels or engineering of gas–liquid interfaces.4.
