  • Patent number: 8944083
    Abstract: A microfluidic device for generation of monodisperse droplets and initiating a chemical reaction is provided. The microfluidic device includes a first input microchannel having a first dimension and including a first phase located therein. The device also includes a second input microchannel having a second dimension and including a second phase located therein. In accordance with the present disclosure, the second dimension is different from the first dimension and the first phase is immiscible in the second phase. A microchannel junction is also present and is in communication with the first input microchannel and the second input microchannel. The device further includes an output channel in communication with the microchannel junction and set to receive a monodisperse droplet. In the present disclosure, the difference in the first dimension and the second dimension creates an interfacial tension induced force at the microchannel junction which forms the monodisperse droplet.

  • Publication number: 20150023809
    Abstract: An ejector includes a nozzle having a fluid passage circular in cross section. The fluid passage includes a throat portion smallest in cross-sectional area, a divergent portion that becomes larger in cross-sectional area toward a downstream side from the throat portion, and an ejection port that is provided at a downstream end of the divergent portion. A passage wall surface of the divergent portion includes a recess portion that is recessed from within outward in a radial direction of the passage wall surface. The recess portion is located adjacent to the ejection port, and the recess portion extends continuously in a circumferential direction of the passage wall surface to enclose the fluid passage and have an annular shape. Accordingly, noise due to an expansion wave of the ejected fluid can be reduced.

  • Publication number: 20140362144
    Abstract: A fluid path structure is manufactured by way of an aligning step of aligning a first resin part with a second resin part by inserting a projection formed on the first resin part into a corresponding hole formed in the second resin part and a welding step of welding joint surfaces of the first resin part and the second resin part, thereby forming a fluid path. The aligning step is executed so as to narrow the gap between the projection and the hole to a minimum at a base side of the projection relative to a half of the height of the hole and the welding step is executed only at the base side of the projection relative to the half of the height of the hole so as to make the lateral surface of the projection only partially contact with the lateral surface of the hole.

  • Patent number: 8905078
    Abstract: Provided is a method of controlling water droplet movement including providing a substrate including a superhydrophobic surface on which a hydrophilic channel guiding water droplet movement is patterned, introducing a water droplet on the substrate, and modulating a slope of the superhydrophobic surface for the water droplet to move on the superhydrophobic surface along the hydrophilic channel. Here, a width of the hydrophilic channel is modulated for the water droplet to move on the superhydrophobic surface having a certain angle with respect to a ground.

  • Patent number: 8758633
    Abstract: Disclosed is a method for fabricating nanofluidic channels having a height of from about 1 nm to about 10 nm. Generally, the method includes formation of doped silicon parallel strips in a silicon substrate, formation of a native oxide layer on the substrate, and etching of the native oxide layer at one of the strips to form a channel of a depth of between about 1 nm and about 10 nm. The method also includes bonding a second wafer to the surface, the second wafer including through etched windows to provide probe contacts to two of the parallel strips during use. These parallel strips provide high-frequency transmission lines in the device that can provide broadband dielectric spectroscopy measurement within the nanochannels.
