Abstract:
1. A method for constructing at least one channel within a preexisting channel of a substrate, the method comprising: providing a substrate, wherein the substrate comprises a preexisting channel; introducing a first fluid and a second fluid into the preexisting channel through a plurality of introductory channels, wherein introducing the first and second fluids comprises attaching a control element to the substrate, wherein the control element comprises the plurality of introductory channels, and wherein the first and second fluids are immiscible; curing the first fluid, wherein curing the first fluid does not cure the second fluid; removing the uncured second fluid from the substrate, thereby constructing at least one constructed channel within the preexisting channel; and repeating the introducing, curing, and removing steps, thereby constructing at least one additional channel within the at least one constructed channel.
