I am pleased to introduce this special issue of the Journal of Fluids Engineering—Transactions of the ASME on microfluidics. The term “microfluidics” is typically used to refer to the study of fluid dynamics in channels or systems with scales of the order of tens to hundreds of microns. The high surface-to-volume ratios and small volumes implicit in a microfluidic system enable engineering functionality that is not possible in a macroscale fluid system. Arguably, microfluidics grew out of both molecular-based fields (molecular analysis and molecular biology) and engineering methods/applications. While the success of microanalytical methods may have led to some of the earliest interest in developing microfluidic systems [1], the involvement of the fluids engineering community grew markedly in the 1990s. During this time period, microelectronics fabrication methods began being leveraged for use in fluid systems and the Defense Advanced Research Projects Agency (DARPA)...
