    摘要: A method for manufacturing an enzymatic reagent ink for use in analytical test strips (such as electrochemical-based analytical test strips configured for the determination of glucose in blood) includes determining a first relationship between wetability of a representative hydrophobic silica material (e.g., a hydrophobic fumed silica material) and at least a first calibration characteristic (for example, a calibration slope) of an analytical test strip that includes an enzymatic reagent ink containing the representative hydrophobic silica material. In the method, the first relationship defines a minimum wetability that provides an acceptable first calibration characteristic. The method also includes determining a second relationship defining wetability of a mixture of a particular hydrophobic silica material and a particular surfactant across a range of relative amount of the particular hydrophobic silica material and the particular surfactant and, subsequently, combining an amount of the particular hydrophobic silica material, an amount of the particular surfactant, and an amount of enzyme (such as glucose oxidase) to form an enzymatic reagent ink. Moreover, the amounts of the particular hydrophobic silica material and the particular surfactant are predetermined based on the second relationship to provide at least the minimum wetability defined by the first relationship.

    摘要: A device for handling a fluid to be introduced into a fluidic device is described. The fluid handling device is designed for alignment with a fluidic device, such as a microfluidic device, where an exit port on the device aligns with one or more apertures in the fluidic for exchange of fluids there between. The fluid handling device includes one or more channels, with at least two pistons spaced apart contained in one or more of the channels. The gap between neighboring pistons define a space between the pistons for containing a fluid. Movement of the pistons from a first position to a second position is effective to move fluid from the fluid handling device into the fluidic device.

    摘要: Methods and apparatus for forming two orthogonally polarized beams of light from an unpolarized beam of light using one of at least two different image modes, the forming includes a color filtering process that is based on the image mode being used, and projecting the two orthogonally polarized beams to form an image on a viewing surface. Methods and apparatus for separating an unpolarized light beam into four beams as a function of wavelength and polarization; selectively modulating the four beams respectively using four light valves; and combining the four modulated beams to generate two orthogonally polarized light beams.
