Microfluidic devices for biological applications are often referred to as "lab-on-a-chip", intended to perform typical laoratory tasks in a software controlled, time and reagent saving manner without the direct interaction of humans. Here, the term "chip" is borrowed from semiconductor based microelectronics. Taking such analogy serious, biochips should be able to run different assays (software) using basically the same hardware. This requires the integration of all necessary components for the assay to be integrated on the chip. Surface acoustic waves (SAW) can efficiently be used to electrically adressable actuate and manipulate small amounts of fluids on a planar surface. In the present project, we wish to investigate the combination and application of such acoustically driven planar chips to conventional three dimensional microfluidic components. Multilayer chip layouts are planned to open the field for programmable low cost bio-labchips.
