Abstract
A microfluidic method and device for focusing and/or forming discontinuous sections of similar or dissimilar size in a fluid is provided. The device can be fabricated simply from readily-available, inexpensive material using simple techniques.
Claims18
A device comprising:
- a microfluidic interconnected region comprising an upstream portion, a downstream portion and a dimensionally-restricted section separating the upstream portion from the downstream portion of the microfluidic interconnected region, the dimensionally-restriction section having a mean cross-sectional dimension that is dimensionally restricted relative to the upstream portion and the downstream portion, the upstream portion comprising a junction of two microfluidic inlet channels each containing a continuous fluid and one microfluidic inlet channel containing a subject fluid, wherein the continuous fluid completely circumferentially surrounds the subject fluid when the continuous fluid and the subject fluid flow through the microfluidic interconnected region.
