Abstract:
We report a microdispenser that can meter and mix sub-nanoliter liquids in a discrete quantity. Our device is based on the structural stopping valve used in passive dispensers. A vent channel was proposed, designed for the autonomous pausing of a metered liquid segment and the seamless joining of the subsequent segments. While the previous microfluidic devices could meter only a single drop, lacking in mixing multiple segments, our approach enables the metering/mixing of different liquids in a discrete ratio. This module will find applications in bio-engineering and pharmaceutical research including large-scale cell differentiation experiment and drug discovery platforms.
