Briefly speaking, “Lab-on-a-chip” is integrating and minimizing bio-chemistry processes and medical inspection in traditional labs into a small and easily-handling chip. The chip includes all lab procedures including sampling, mixing, transport, splitting and detection etc. Its advantages are the automation of sample handling, the reduction of the need of human resource, and the avoidance to manual interference and direct exposure to harmful chemistry reagents. Since the chip only needs few amounts of sample and reagent (below ~1 μl in common), the need of sample and reagent, the pollution of chemical reagents, and the cost can be greatly reduced and improved. Besides, it also effectively enhances the efficiency, repeatability and accuracy of experiments.

The 70% composition of human body is “fluid” including water, blood, and tissue fluid etc. All fluids flowing inside human body rely on each own specific and complicated physiological mechanisms. As to Lab-on-a-chip, the fluid transportation is also a basic and essential function. Like the heart driving the blood flow inside the vessel, micropump is the driving power source of fluid on the chip. At present, based upon the fundamental study of micropump in past few years, our team devote to developing the corresponding core-technology as a product, and choosing “drug delivery” as the first target.
