The development of minituarized total chemical analysis systems (µTAS) over the past decade has revolutionalized the way scientists can address a variety of chemical and biological problems. Lab-on-a-Chip combines analytical detection techniques and fluid management into a chip format. The miniaturization of systems has clear advantages compared to their conventional counterparts, improving their efficiency in terms
of sample size, response times analytical performance process control and throughput [1].
The Lab-on-a-Disc concept combines the advantages of the Lab-on-a-Chip without the need of interconnections to the outer world. The fluid pumping is achieved by simply spinning the disc while the control of flow is achieved with the proper design of channels and valves [2].
