  • Publication number: 20150093775
    Abstract: An analyte sensing and monitoring system and method is provided that is particularly applicable to monitoring of analytes in cell cultures. The system and method relies on the initial diffusion rates of the analytes from the medium that contains the analytes being measured (e.g., cell culture) into a diffusion chamber that is inserted into the medium, and remote sensing of the analytes using an analyte sensing system that is coupled to the diffusion chamber.

  • Patent number: 8993972
    Abstract: A fluorescence based sensor system that provides improved signal-to-noise over prior systems is provided. The system includes a fluorescence based sensing medium that is contained a recessed cavity with reflective sides that allow for more uniform excitation of the fluorescence based sensing medium by the excitation light.

  • Patent number: 8654319
    Abstract: A low cost sensing system that can measure both chlorophyll concentration and turbidity is provided. The system is an optical system that utilizes at least three light sensors for measuring side-scattered and forward scattered light, as well as fluorescence. The system is able to take optical density measurements, steady state fluorescence measurements and maximum fluorescence measurements, and can be configured for wireless control and data transmission. The system may also be housed in one or more fluidtight housings so as to make it submersible.

  • Publication number: 20130281806
    Abstract: A non-invasive gas analyte sensing and monitoring system and method is provided that is particularly applicable to transcutaneous monitoring of arterial blood gases in a mammal. The system and method relies on diffusion of the analyte to be measured into a diffusion chamber and remote sensing of the analyte in the diffusion chamber using optical chemical sensors and associated optoelectronics.

  • Publication number: 20130253295
    Abstract: Systems and methods for determining an in vivo concentration of a small molecule substance of interest is provided that takes advantage of the semi-permeable nature of skin, which allows small molecules to passively diffuse through the skin and onto the skin surface. The systems and methods of the present invention allow for the collection of these small molecules that have passively diffused through the skin without skin disruption or breaking of the skin. The systems and methods of the present invention are noninvasive, painless and safe even for delicate newborns, and are particularly suited for the determination of blood glucose in newborns and infants in a noninvasive manner.

  • Patent number: 7718353
    Abstract: A protein sensing molecule is capable of binding an analyte in a sample. The protein sensing molecule includes a first detectable quality that changes in a concentration dependent manner when the protein sensing molecule is bound to the analyte. The protein sensing molecule also includes a second detectable quality that does not undergo substantial change when the protein sensing molecule is bound to the analyte. The protein sensing molecule may be used in methods for characterizing samples and may also be used in sensors.

  • Publication number: 20060286165
    Abstract: The present invention provides a taste-masked pharmaceutical particle prepared by a polymer blending process, a process for preparing the particle, and the use of the particle in preparing the orally disintegrating tablets. In this process, a micronized active drug ingredient is mixed with three kinds of pharmaceutically acceptable polymer adjuvants to yield a complete and uniformly mixed sheet with smooth surface and good plasticity. The sheet is knocked into small blocks, and then pulverized and pelleted to yield a taste-masked pharmaceutical particle whose bitter or peculiar taste is not felt in 120 s. The taste-masked particle can release the drug in a very high speed in an acidic solution (pH=1.0) and release the drug in a high speed in a solution with low acidity (pH=4.0), and effectively disperse in a solution with very low acidity (pH=6.8).
