Microfluidics/Introduction

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? frame|50px|right|Head of an ink jet printer 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.
