1. A method for evaluating embryos, the method comprising steps of:
- placing an embryo in an approximately embryo scaled fluid channel;
creating a fluid flow in the fluid channel; and
evaluating an embryo characteristic while an embryo is within the embryo scaled fluid channel.

Abstract
Microfluidic embryo scaled channels for handling and positioning embryos provide the opportunity to evaluate and treat embryos in improved manners Fluid flow is used to move and position embryos within microfluidic channels and channel geometries may be used to place embryos at specific locations. Surface properties and compliance (deformation) properties of embryos are evaluated as a predictor of viability. The microfluidic channels provide the opportunity for fine controls of pressure to conduct various evaluations at forces slightly below which damage to embryos is known to occur.
