What is microfluidics?
Microfluidics is the science of fluid flows at the microscopic scale.

Microfluidics mainly deals with artificial systems, but is present in numerous natural systems:
 * Trees: ascent of sap in xylem conduits in the trunk (conduit diameter around 30 micrometers), and in leaves (diameter around 50 nanometers).
 * Inside us: capillary blood vessels transport liquid (diameter 8 micrometer), lungs pump air in small alveola.

Why do we care?


Microfluidic is involved in present applications:
 * Top one: ink-jet printer

Starting applications with a promising market are:
 * medical implants (injection of drugs from an embedded pump)
 * Lab-on-a-chip: miniature lab to perform biological test such as proteomics, or chemical analysis/synthesis of very exothermic reactions

For research purposes, it provides miniature devices to study small objects.
