  • Publication number: 20210001340
    Abstract: The invention provides a microdroplet- or bubble-producing device that does not require separate through-holes for different liquid droplet/air bubble-producing flow channels. The droplet-producing flow channels are configured in a three-dimensional manner unlike in a conventional device where they are configured in a two-dimensional plane, and therefore the flow channels can be provided in a more high-density configuration than the prior art.
