When the field of microfluidics emerged in the early 1990s, it was primarily focused on the development of analytical microdevices. Since then, microfluidics has expanded its influence into virtually every branch of science and engineering. There are many driving forces behind this explosive growth. To name a few: • Scaling properties afforded by miniaturization are desirable for many applications. For example, enhanced mass transfer and heat dissipation enable faster chemical separations without sacrificing separation performance
