Abstract:
1. A method comprising: preparing a substrate including a plurality of material-feeding microchannels with a width of 1000 μm or less and a reaction micro channel with a width of 1000 μm or less connected to the plurality of material-feeding microchannels; feeding a first fluid containing a substance into a first one of the plurality of material-feeding microchannels; feeding a second fluid containing an envelope-forming material into a second one of the plurality of material-feeding microchannels; feeding third fluid containing neither the substance nor the envelope-forming material into a third one of the plurality of microchannels; converging the first fluid, the second fluid and the third fluid from each of the first, the second and the third material-feeding microchannel to the reaction microchannel, wherein the third fluid flows in the center of the reaction microchannel and separates the first fluid and the second fluid continuously along the length of the reaction microchannel; forming a microcapsule having a diameter of 1 μm or less by encapsulating the substance within the envelope-forming material in the third fluid; and collecting the fluid containing the microcapsule flowing through the reaction microchannel.
