Abstract :
A new capillary pressure technique is developed that supports the controlled handling of liquids in Lab-on-a-Chip systems. Capillary pressure barriers, called phaseguides, are used to enable controlled patterning of gel and sample. In this paper design rules are defined for phaseguide pattering and several applications are discussed.
