Abstract: A sensor may include a membrane to deflect in response to a change in surface stress, where a layer on the membrane is to couple one or more probe molecules with the membrane. The membrane may deflect when a target molecule reacts with one or more probe molecules.

Abstract: An automatic synthesis machine is used for synthesis of compounds using a plurality of vessels, allowing reagents to chemically react with each other. The automatic synthesis machine comprises a selection means for selecting a specific vessel among a plurality of vessels, a display device for displaying the vessel selected by the selection means in a manner such that it can be identified, together with the operation contents (suction and injection) related to the selected vessel, and an analysis means for analyzing a protocol prescribing a series of operational procedures for synthesis of compounds and picked-out commands related to the selected vessel from the protocol.

Abstract: 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.

Abstract: A system for the rapid characterization of multi-analyte fluids, in one embodiment, includes a light source, a sensor array, and a detector. The sensor array is formed from a supporting member into which a plurality of cavities may be formed. A series of chemically sensitive particles are, in one embodiment positioned within the cavities. The particles may be configured to produce a signal when a receptor coupled to the particle interacts with the analyte. Using pattern recognition techniques, the analytes within a multi-analyte fluid may be characterized.

Abstract: Serial and parallel dispensing tools that can deliver defined and controlled volumes of fluid to generate multi-element arrays of sample material on a substrate surface are provided. The substrates surfaces can be flat or geometrically altered to include wells of receiving material. Also provided are tools that allow the parallel development of a sample array. To this end, the tool can be understood as an assembly of vesicle elements, or pins, where each of the pins can include a narrow interior chamber suitable for holding nanoliter volumes of fluid. Each of the pins can fit inside a housing that forms an interior chamber. The interior chamber can be connected to a pressure source that will control the pressure within the interior chamber to regulate the flow of fluid within the interior chamber of the pins. The prepared sample arrays can then be passed to a plate assembly that disposes the sample arrays for analysis by mass spectrometry.

Abstract: The present invention provides microfluidic devices that comprise a body structure comprising at least a first microscale channel network disposed therein. The body structure has a plurality of ports disposed in the body structure, where each port is in fluid communication with one or more channels in the first channel network. The devices also include a cover layer comprising a plurality of apertures disposed through the cover layer. The cover layer is mated with the body structure whereby each of the apertures is aligned with a separate one of the plurality of ports.
