More Information
Summary:A diagnostic and analytical apparatus including the microfluidic device having: an inlet portion with a first cross-section, a flow delaying portion with a second cross-section that is larger than the cross-section of the inlet portion thereby reducing the interfacial curvature of the microfluid entering from the inlet portion by capillary force and the flow rate of the microfluid, and a flow recovery portion having a third cross-section that is smaller than the cross-section of the flow delaying portion. The flow of a very small volume of fluid can be quantitatively regulated through a channel having a particular design that can induce spontaneous flow by capillary force without additional manipulation processes and energy requirement.
