Abstract: Techniques comprising systems and methods for forming or pattering microstructures using microfluidics are described. A target structure can include a microchannel passage with a chamber into which a light hardenable material can be injected and selectively exposed to light to adhere to a desired location of a substrate. Unhardened material can be washed out of the chamber. One or more subsequent cycles can repeat the process using the same or a different material. A variety of composite microstructures can be created, including structures encapsulating viable living cells, such as for cell study or tissue engineering.
