The recent developments of microfluidics have revolutionized many fields of sciences and technologies such as chemistry and biology, with applications of genomics and proteomics; lab-on-chip-analysis; micro-quantity syntheses; clinical diagnoses and on-line analysis of reaction processes, environment monitoring, etc. Increased demands for microfluidic will dramatically increase the range of applications for microsystems.

Microfluidics deals with the transfer and control of small amount (nano or pico liter range) of fluids in microscale flow configurations, which makes the manipulation of cells and macro molecules become possible in the micro channels/reactors in integrated system. The matching between the length scales of the flow and the cells/micro-particles affects directly the efficiencies of momentum and energy transfer of the motions. The small transverse length scale in microfluidic system produces very small Reynolds number with high velocity gradient and high viscous force, which is much different from the macro flows with higher inertia of fluid mass. If the size further reduced to nano-scales, the hypothesis of continuum becomes questionable. The surface effect on the motion of the cell/molecules near the solid boundary can be dominating. The size effects due to the large surface to volume ratio is evident in this flow regiem. Driving forces in eh microsystem may need to combine the hydrodynamic pressures and the electrokinetics force.These aforementioned phenomena are interesting topics in micro/nano fluidic researches. Due to the change of force fields in the large range of length scales, the development of proper models and theories becomes more and more important for the interpretation the interesting phenomena in micro flow and for the exploration of optimal design and fabrication of microfluidic systems.


In this summer school, the research achievements in this field during recent years will stimulate the interests of young scholars and students to enter the field of this challenging technology. The topics of the lectures include:

• Size and surface effects in microfluidics and their influences on macro-parameters of fluid mechanics
• Action and coupling of hydrodynamic pressures and electrokinetic force fields in flow control of microfluidic system.
• Innovative pattern design and flowing analysis in the manipulation of cells, molecules and DNA/RNA.
• Measurement methodologies and techniques in microfluidic mechanics such as optical detection and micro particle image velocimetry
• Computational simulations of microfluidic mechanics with advanced models and algorithms.
• Mechanics related to the microfluidic applications of mixing, separation, filtering, sensing and actuating in MEMS and Nano devices.
