Microfluidics
9/17/2008
“Microfluidics deals with the behavior, precise control and manipulation
of
fluids that are geometrically constrained to a small, typically
sub-millimeter, scale. Typically, micro means one of the following
features:
small volumes(nl, pl, fl)
small size
low energy consumption
effects of the micro domain”

Notes
“It is a multidisciplinary field intersecting engineering, physics, chemistry, microtechnology and biotechnology, with practical applications to the design of systems in which such small volumes of fluids will be used. Microfluidics has emerged in the beginning of the 1980s and is used in the development of inkjet printheads, DNA chips, lab-on-a-chip technology, micro-propulsion, and micro-thermal technologies.”

“The behavior of fluids at the microscale can differ from 'macrofluidic' behavior in that factors such as surface tension, energy dissipation, and fluidic resistance start to dominate the system. Microfluidics studies how these behaviors change, and how they can be worked around, or exploited for new uses.”
“At small scales (channel diameters of around 100 nanometers to several hundred micrometers) some interesting and unintuitive properties appear. The Reynolds number, which characterizes the presence of turbulent flow, is extremely low, thus the flow will remain laminar. Thus, two fluids joining will not mix readily via turbulence, so diffusion alone must cause the two fluids to mingle.”

Microfluidic structures include micropneumatic systems, i.e. microsystems for
the handling of off-chip fluids (liquid pumps, gas valves, etc), and
microfluidic structures for the on-chip handling of nano- and picolitre volumes.
The commercially most successful application today is the inkjet printhead.
