Microfluidics

Microfluidics deals with the behaviour, precise control, and manipulation of fluids that are geometrically constrained to a small (typically sub-millimeter) scale. It is a multidisciplinary field intersecting engineering, physics, chemistry, microtechnology and biotechnology, with practical applications to the design of systems in which small volumes of fluids will be used. Microfluidics is used in the development of inkjet printheads, DNA chips, lab-on-a-chip technology, micro-propulsion, micro-thermal technologies and micro-chemical reactors.
