Abstract
Isotachophoresis (ITP) is a well established method for the separation of single species from complex mixtures. We show that ITP can also be applied for realizing further microfluidic operations, such as the merging and mixing of multiple samples. Using FEM simulations we investigate such ITP contacting and analyse the relevant time scale. Furthermore, combining the self-sharpening effect of ITP with electroosmotic flow (EOF) facilitates the transport of well defined, 'digital' sample plugs. Both aspects could lay the foundation for novel single-phase digital microfluidics.
