Abstract: A device for sensing analyte concentration, and in particular glucose concentration, in vivo or in vitro is disclosed. An optical conduit, preferably an optical fiber has an optical system at the proximal end of the optical conduit. A sensing element is attached to the distal end of the optical conduit, and comprises at least one binding protein adapted to bind with at least one target analyte. The sensing element further comprises at least one reporter group that undergoes a luminescence change with changing analyte concentrations. Optionally, the sensing element includes reference groups with luminescence properties that are substantially unchanged by variations in the analyte concentrations.

Abstract: Coated nanoparticles comprising a core surrounded by a shell that increases the reflectance of the nanoparticle, wherein the coated nanoparticle does not include a Raman-active molecule, are provided. Test devices and immunoassay methods utilizing the coated nanoparticles are provided.

Abstract: A method is disclosed for accurately determining the concentration of a target analyte utilizes reagent pairs having different affinity for the target. The different affinity provides distinct binding profiles that can be analyzed to absolutely determine the analyte concentration. The method provides an assay system having expanded dynamic range to cover a wider range of analyte concentration and can overcome the hook-effect that commonly exists in homogenous assay systems. The method utilizes distinguishable signals that allows for the analysis of multiple binding profiles and multiplex analysis.

Abstract: The present invention relates to methods of making a sterilized biosensor, where the biosensor comprises at least one binding reagent, which comprises at least one non-enzyme proteinaceous binding domain. Certain embodiments of the methods described herein comprise partially assembling the components of the biosensor, except for the binding reagent, and separately sterilizing this partial assemblage and the binding reagent. The sterilized binding reagent and the sterilized partial assemblage are then aseptically assembled to produce the sterilized biosensor. Other embodiments of the methods described herein comprise assembling substantially all of the components of the biosensor, including the binding reagent, and sterilizing the assembled biosensor to produce a sterilized biosensor.

Abstract: An automated fluid formulating system for use in small scale laboratory operations. The system utilizes a computer to provide precise control over the measurement of ingredients and the entire formulating process. The novel feature of this invention is that it can provide precise control over the formulating of high viscosity, high solid fluids, such as emulsions and gels. Further, a pre-programmed cleaning cycle can be input into the computer to automatically clean the mixing elements so that the mixing elements do not contaminate subsequent formulations with materials from the prior formulation.
