Abstract

To realize integrated multi-step Micro Total Analysis Systems (μTAS), pneumatic manipulation of reagent droplets is a promising scheme. In this scheme, passive vent valves are required for positioning and mixing of the droplets. This paper presents a novel microstructure named Hydrophobic Microcapillary Vent (HMCV). An array of hydrophobic microcapillaries allows air passing through it, whereas it stops liquid by negative capillary action. Test structures have been fabricated by molding technique of silicone elastomer. Positioning and mixing functions of droplets with pL-nL volume are demonstrated.
