Abstract
A microfluidic embryo handling device and method in which biological rotating of embryos is simulated. Fluid flow is used to move and position embryos without assistance of electrical stimulus or other means which may produce undesired heating of biological medium used as the fluid for transporting and position. Continuous or pulsed flow is maintained around an embryo or embryos in the device. The device provides an excellent simulation of biological conditions and may be used for culturing, sorting, testing, evaluating, fertilizing and other similar typical handling operations. An embryo may be parked at a desired location to carry out such a typical operation, while the microfluidic handling device maintains fluid flow around the embryo.
