    摘要: A droplet sample holder, especially a sample holder for use in a measuring instrument utilizing surface plasmon resonance. The sample holder reduces or minimizes the measurement distortion result of the droplet “pherpheral concentration effect” by surrounding the analysis zone with a wettable (hydrophilic) zone that captures the periphery of the droplet to keep the pheriphery of the droplet and the increased concentration of the analyte out of the analysis zone. The wettable zone is surrounded by a nonwettable (hydrophobic) zone that restricts the periphery of the droplet to analysis zone and the wettable zone.

    摘要: An assembly design for an oscillating resonator-based sensor where an oscillating crystal resonator such as a quartz crystal resonator is rigidly affixed or ‘mounted’ onto a solid substrate in such a fashion that the resonator can either rest flush against the substrate surface or upon a rigid mounting adhesive. Once cured, the mounting adhesive forms a liquid tight seal between the mounted resonator and the substrate such that only the sensing electrode surface will be exposed to fluids applied to the front side of the substrate. The mounted resonator assembly is designed in such a way that it can be interfaced with a fluid delivery system to form a liquid tight chamber or flow cell around the mounted resonator without incurring additional physical impact upon the mounted resonator. The assembled flow cell can in turn be used to direct multiple fluid streams to flow in a laminar manner over the sensing surface of the mounted resonator and by varying the rates of flow for the different laminar flowing fluid streams the total hydraulic pressure exerted on the surface of the mounted resonator can be held constant.

    摘要: The present invention is a flow cell and method for use in microfluidic analyses that presents highly discrete and small volumes of fluid to isolated locations on a two-dimensional surface contained within an open fluidic chamber defined by the flow cell that has physical dimensions such that laminar style flow occurs for fluids flowing through the chamber. This process of location specific fluid addressing within the flow cell is facilitated by combining components of hydrodynamic focusing with site specific cell evacuation. The process does not require the use of physical barriers within the flow cell or mechanical valves to control the paths of fluid movement.
