Abstract
A microfluidic device adapted such that the flow of fluids within the device is controlled by different surfaces of the device having different surface characteristics. Preferably the device comprises a substrate not formed from a hydrated oxide material.
Claims6
1-19. (canceled)
A microfluidic device comprising:
- (a) a solid substrate,
- (b) formed in the substrate, a channel network having
- (i) one or more reservoirs, and
- (ii) one or more capillary channels connecting the reservoirs in fluid communication with one another,
- said network having wall portions that are sufficiently wettable to promote flow of a liquid in the network by capillarity along such wall portions, and
- (c) formed on at least one of said wall portions, a non-wettable region effective to block liquid flow by capillarity past or through said non-wettable region.
