Methods for modulation of flow in a microfluidic pathway

摘要

Method for modulating the flow of a liquid comprising
introducing liquid to a flow modulation pathway having a hydrophobic region (50) in contact with a capillary passage (35) comprising at least one stepped-down junction (36a,36b), whereby said liquid is stopped in an area of said pathway that includes said hydrophobic region (50) and said at least one stepped-down junction (36a,36b).
