    Abstract

    A pneumatically-driven, microfluidic-based, disposable, polycarbonate cassette for DNA amplification and detection is described. The cassette consists of a monolithic - polycarbonate microfluidic chip and a lateral flow (LF) strip. The chip contains a polymerase chain reaction (PCR) chamber and a mixing/incubation chamber. The flow control was realized with phase-change valves that can operate in self-actuated mode and do not require any moving parts. The fusion and mixing of two liquids were achieved by pre-freezing the mixing chamber. Tests with B. cereus genomic DNA demonstrated that the performance of the cassette compared favorably with bench-top protocols.
