Microfluidics and microfluidic devices

Microfluidics deal with the flow of liquids inside micrometer-sized channels. In order to consider it microfluidics, at least one dimension of the channel must be in the range of a micrometer or tens of micrometers (see the difference between nanofluidics, microfluidics, millifluidics and the behavior of fluids at these scales). Microfluidics can be considered both as a science (study of the behavior of fluids in micro- channels) and as a technology (manufacturing of microfluidics devices for applications such as lab- on-a-chip).
