This paper presents the basic concepts related to the newly emerging field of microfluidics. Following a brief introduction of the general conservation and particular laws, three size effects are introduced. The velocity slip boundary condition for gas flows as well as the electrokinetic and polar-mechanics effects for liquid flow in microdomains are introduced. Pressure-driven gas flows and electrokinetically-driven liquid flows in microchannels are analyzed in details. Finally, several flow diagnostic techniques and fabrication of microfluidic systems are described.
