  • Fluidic patterning of hydrogel partitions
    Patent number: 11090651
    Abstract: The present technology provides spontaneous capillary flow devices for patterning walls on a hydrophilic substrate. In some embodiments, the devices include rails having a first end portion for receiving a flowable material, a second end portion opposite the first end portion, and a base portion having a flow surface extending between the first end portion and the second end portion. The flow surface can face the hydrophilic substrate and define a flow path. When the flowable material is released into the first end portion, the flowable material flows via spontaneous capillary flow from the first end portion to the second end portion along the flow path to create a partition on the hydrophilic substrate.
