Abstract
An embodiment for a microfluidic device is provided. The device comprises two areas, arranged side-by-side, and a trigger channel. They include a first area, which is delimited by a first liquid pinning barrier, and a second area, which is delimited by a second liquid pinning barrier. The latter extends parallel to the first liquid pinning barrier to delimit a corridor. The trigger channel extends through the corridor between the two areas. In addition, the trigger channel connects the first liquid pinning barrier with the second liquid pinning barrier, allowing a first liquid pinned at the first liquid pinning barrier and a second liquid pinned at the second liquid pinning barrier to be contacted, each, by a reverse flow of the second liquid in the trigger channel and thereby start mixing at a level of the corridor, in operation. The invention is further directed to related methods of operation.
