Abstract: A microfluidic device for analysing a fluid sample comprises at least one sample transmission channel; at least one multi-functional channel; and at least one reactor module which provides a fluid connection between the sample transmission channel and the multi-functional channel. Each reactor module comprises at least one reaction chamber, having at least one inlet in fluid communication with the sample transmission channel(s); and at least one fluid isolation chamber, which is in fluid communication with the outlet(s) of the reaction chamber(s). The fluid isolation chamber serves to isolate the fluid sample from the multi-functional channel(s).

Abstract: The present invention relates to a device and an apparatus device for processing a biological and/or chemical sample. The device comprises at least one sample processing chamber having an inlet at a first end and a penetrable sealing layer at a second end that forms at least a part of an inner wall of the sample processing chamber. The sealing layer is adapted to seal off the sample processing chamber from the environment until said sealing layer is penetrated to form an outlet. The device and apparatus also includes an absorption layer, wherein upon penetration of said sealing layer, said absorption layer is in fluid contact with said sealing layer and is capable of absorbing fluid released from said sample processing chamber, via the outlet. The present invention also relates to a fluid separation device. The fluid separation device comprises a penetrable sealing layer adapted to form a wall of a sample processing chamber of the device of the invention.

Abstract: A micro-pump having a first layer, a second layer and an intermediate flexible layer is disclosed. The first layer and second layer may be of moldable plastics. The intermediate layer may be a substantially flat PDMS membrane layer having an inlet hole and an outlet hole. The first layer and the second layer are disposed on either side of the intermediate layer to define a pumping chamber that encloses an actuatable portion of the intermediate layer and valve seats that abut the inlet hole and the outlet hole of the intermediate layer. The actuatable portion is moveable to increase and reduce the volume of the pumping chamber to allow pressure to lift the respective intermediate layer portions surrounding the inlet hole and the outlet hole to thereby draw fluid and expel fluid from the pumping chamber respectively.
