Rapid Prototyping in Copper Substrates for Digital Microfluidics

is a barrier to its growth and development. Conse-quently, DMF devices are limited to use in a few laboratoriesworldwide.The availability of an accessible microfabrication techniqueis critical for the growth and continued development of DMF.An analogy can be made to the state of conventional, chan-nel-based microfluidics in the mid-1990s. A database searchreveals that approximately eight articles per year were pub-lished on the subject of channel microfluidics in 1992–1998;this number exploded to approximately 53 articles per yearin 1999–2000.
