    摘要: An integratable fluid flow and property microsensor assembly is configured to be operably embedded in a microfluidic cartridge of the type used in lab-on-a-chip systems. The assembly is a robust package having a microstructure flow sensor contained within a housing in order to achieve a robust sensing device. The cartridge provides a flow path to the assembly, which directs the fluid across the flow sensor and returns the fluid to the cartridge flow path. The flow sensor monitors the controlled flow of fluid and transmits signals indicative of that flow. The assembly structure provides a robust sensor that is operable and accurate in many different applications.

    摘要: A hematology analyzer or cytometer cartridge system having flow metering. It may have on- or off-cartridge flow metering and control. The system may have local and direct flow measurement to provide accurate counts per unit volume. There may be numerous arrangements for fluidic circuit checks of the cartridge. Examples may include checks pertaining to zero flow, interface, pressure, flow rate, fluid type and quality, backflow, dry qualification, temperature exposure limits, and so on, of the circuits and cartridge associated items.

    摘要: A microfluidic cartridge that includes at least one reservoir for storing a reagent or the like for an extended period of time. In one illustrative embodiment, at least part of a wall of a reservoir includes a hydrophobic material, such as a polymonochlorotrifluoroethylene (PCTFE) homopolymer and/or copolymer. The hydrophobic material may help reduce leaching, evaporation, diffusion and/or other transfer of the reagent or one of its components from the reservoir. When the reagent or the like is lyophilized, the hydrophobic material may help keep water, water vapor and/or other gases or liquids from entering the reservoir prior to use of the microfluidic cartridge.

    摘要: A method and apparatus for enabling chemical identification of individual particles, cells of molecules by obtaining a Raman spectrum of a particle, cell or molecule as it flows past a sensing point in a flow cytometer. The particles, which may be cells or molecules, are associated with a suitable noble metal colloid or colloidal aggregate. Cellular particles may be associated with gold or silver colloidal particles by ultra-sonic sonification while in a sample preparation reservoir containing the gold or silver colloidal suspension. The colloid associated particles are then hydrodynamically focused into a single file by a fluid control module. The surface-enhance Raman Spectrum of individual particles are obtained by illuminating the particle with a laser as the particle flows past a sensing point and gathering the light that is non-elastically scattered (Raman scattered) by the particle. The surface-enhanced Raman spectrum is then analyzed to identify the particle.
