Devices we freely supported electroactive membranes and embedded microfluidic channels are disclosed herein. Methods of fabricating such devices utilize multilayer polymer micromachining to form integrated membrane and microfluidic structures.

A method measuring the phase transition characteristics of a macromolecule, the method comprising: generating a stream of micro-droplets comprising at least one constituent, of which one constituent comprises the macromolecule, varying the conditions in the micro-droplets; and measuring the relative concentrations of the constituents of, and the phases of the macromolecule present in, the micro-droplets.

Lateral flow devices, methods and kits for performing lateral flow assays are provided.

The present invention provides methods and devices for simple, low power, automated processing of biological samples through multiple sample preparation and assay steps. The methods and devices described facilitate the point-of-care implementation of complex diagnostic assays in equipment-free, non-laboratory settings.

A lateral flow assay (LFA) device includes a capillary pad and a sample port that holds the sample fluid before a hole is made in a cavity surface of the sample port. The LFA device includes a breaker with a tip to make a hole in the cavity wall of the sample port causing the sample fluid held inside the compartment to be applied to the capillary pad after the start of a test.

The present invention is directed to a cartridge device for a measuring system for measuring viscoelastic characteristics of a sample liquid, in particular a blood sample, comprising a cartridge body having at least one measurement cavity formed therein and having at least one probe element arranged in said at least one measurement cavity for performing a test on said sample liquid; and a cover being attachable on said cartridge body; wherein said cover covers at least partially said at least one measurement cavity and forms a retaining element for retaining said probe element in a predetermined position within said at least one measurement cavity. The invention is directed to a measurement system and a method for measuring viscoelastic characteristics of a sample liquid.

A fluidic system for fraction collection comprises a switching valve having a plurality of ports for connecting first and second ports in different configurations. An inlet line is directly connected to the first port, and a collection device is directly connected to the second port. In a collection configuration, the first port and the second port are connected. The ports further comprise third and fourth ports, and the fluidic system further comprises a buffer section directly connected to the third and fourth ports. The fluidic system further comprises a first collection reservoir and is configured to position the collection device to expel a fluid into the first collection reservoir. In a buffer configuration, fluid flows through the inlet line, the first port, the third port, the buffer section, the fourth port, the second port, and the collection device.

In accordance with one embodiment, a processing device includes a heated internal wall and a rotating rod positioned within an interior space formed by the heated internal wall. The rotating rod may be hollow and act as an internal heat exchanger. The processing device also includes a plurality of baffles spaced apart from one another along the rotating rod and extending away from the rotating rod towards the heated internal wall. The processing device also includes at least one wiper or roller coupled to an edge of at least one of the plurality of baffles or porous, packed basket, coupled to the rotating rod and that contacts the heated internal wall while rotating together with the rotating rod. In another embodiment, a processing device may be used to adsorb reactive gases into a liquid phase while heat is exchanged.
