Method for mixing fluids in microfluidic systems

摘要

A method for mixing liquids on a microfluidic level comprises the steps of rotating a coupon to impart flow via centripetal force to a first liquid through a microchannel in the coupon to inject the first liquid into a mixing chamber to mix the first liquid with a second liquid, withdrawing a quantity of the first and second liquids from the mixing chamber, and injecting at least a portion of the quantity of the first and second liquids into the mixing chamber to further mix the first and second liquids.
