Abstract
A method for conveying at least one first medium within a channel system of a fluidic device includes providing the at least one first medium at a first point in the channel system, conveying the at least one first medium from the first point to a second point of the channel system by means of at least one second medium which borders the at least one first medium, and altering at least one traversable cross-section of the channel system for a peristaltic pump function only at a time when the at least one first medium is not flowing through said at least one cross-section.

A method for conveying at least one first medium within a channel system of a microfluidic device, comprising:
- providing the at least one first medium at a first location of a channel of the channel system, the first location spaced apart from at least one fluid inlet of the channel;
- conveying the at least one first medium from the first location to a second location of the channel of the channel system by configuring at least one valve for peristaltic pumping of only at least one second medium, the second location different from the first location and the at least one fluid inlet, the at least one second medium adjacent to the at least one first medium, the peristaltic pumping of the at least one second medium configured to cause movement of the at least one first medium in the channel from the first location to the second location;
- configuring the at least one valve for the peristaltic pumping only when the at least one second medium flows through the at least one valve and not when the at least one first medium flows through the at least one valve, and
- configuring the at least one valve in an open position when the at least one first medium flows through the at least one valve, and
- serially opening and closing the at least one valve to configure the at least one valve for peristaltic pumping of the at least one second medium.
A method for conveying at least one first medium within a channel system of a microfluidic device, wherein comprising:
- providing the at least one first medium at a first location of a channel of the channel system, the first location spaced apart from at least one fluid inlet of the channel;
- conveying the at least one first medium from the first location to a second location of the channel by peristaltic pumping at least one second medium using at least one valve, the second location different from the first location and the at least one fluid inlet, the at least one second medium adjacent to the at least one first medium, the peristaltic pumping of the at least one second medium configured to cause movement of the at least one first medium in the channel from the first location to the second location;
- and
- configuring the at least one valve for the peristaltic pumping only when the at least one second medium flows through the at least one valve and not when the at least one first medium flows through the at least one valve,
- wherein the movement of the at least one first medium is monitored based on a degree of filling of a chamber by at least one third medium,
- wherein the peristaltic pumping of the at least one second medium is configured to cause movement of the at least one third medium, and
- wherein the chamber is fluidly connected to the channel.

- configuring the at least one valve for the peristaltic pumping only when the at least one second medium flows through the at least one valve and not when the at least one first medium flows through the at least one valve;
- and
- monitoring the movement of the at least one first medium using at least one third medium,
- wherein the at least one third medium is adjacent to the at least one second medium.
