• techniques [1]. For scales of 100 µm and above, even plain paper was proposed as an inexpensive substrate for microfluidic devices [2][3]. However, when downsizing microarrays to the lower micrometer range with spot features in the range of a few tens of micrometres, the intrinsic granularity and broad pore

• has been coupled to microfluidic devices as an in-line analytical technique [15][16][17]. In these instances all the flow was fed directly to the MS to ensure high enough flow and concentration for efficient detection, but whereby the sample cannot be regenerated due to the nature of MS.

Due to its excellent gas permeability this polymer has been applied as a membrane for gas separation [15]. In our work, we combine free

• designing artificial cilia that would act as pumps and mixers in microfluidic devices. The artificial cilia would be periodically driven by an external force, for example by an electric or a magnetic field, and as long as it beats in an asymmetric manner, it should generate flow. Initial attempts to create

A common example is their employment in microfluidic devices: Due to their permanent magnetic moment, they can be controlled via external, inhomogeneous magnetic fields [2] and also be detected by magnetoresistive sensors [3] which allows for the magneto-based
