Background

Microfluidics offers many advantages, such as automatically performing assays and minimal reagent usage. Most lab-on-a-chip systems, however, still require interfacing with macroscale tubes for pressure driven fluid handling. This inhibits scalability and parallelization and requires excessive power consumption.
