A microfluidic device which operates without the need for an external power source. The device includes a body structure, at least one microscale channel within the structure, a port for introducing fluid into the channel, and a power source internal to the structure for propelling the fluid through the channel. Various structures are described which embody the invention.

Pumpless microfluidics

A valve for use in microfluidic structures. The valve uses a spherical member, such as a ball bearing, to depress an elastomeric member to selectively open and close a microfluidic channel. The valve may be operated manually or by use of an internal force generated to shift the spherical member to its activated position.

Valve for use in microfluidic structures

A device for analyzing sample solutions such as whole blood based on coagulation and agglutination which requires no external power source or moving parts to perform the analysis. Single disposable cartridges for performing blood typing assays can be constructed using this technology.

Microfluidic analysis cartridge

A valve for use in laminated plastic microfluidic structures. The valve comprises first, second, and third layers of flexible material separated by first and second spacing layers to form microfluidic channels, and having an actuator section to selectively isolate the microfluidic channels from each other. The structure can also be used as a recirculating pump.
