10.3. Microfluidic Devices

Microfluidic systems are a part of life science technology and diagnostic and therapeutic biomedical engineering. Passive micro components like capillary micro channel structures and so-called wells, reservoir areas, or miniaturized sample chambers can be part of micro total analysis systems (μ-TAS) or lab-on-a-chip systems [15]. Representative of passive microfluidic systems are, for example, capillary electrophoresis chips. Active microfluidic components like pumping systems or valve systems are mostly part of complex total analysis systems.

10.3.1. Capillary Analysis Systems

The functioning of a capillary electrophoresis system can be explained principally by Fig. 10.12. The system consists of two intersecting ...
