  • Patent number: 7300800
    Abstract: An analyte detection system utilizing a combination of fluorescent labels for labeling particles and an analyte specific fluorescent analyte detection dye. The particles contain a combination of fluorescent labels for coding the particles and an analyte specific fluorescent dye. The particles can be used to identify and quantify analytes in an analytical sample by reaction of the analytical sample with the particles. An analytical device can identify the particles according to the combination of fluorescent labels. The device can then correlate the identified particle with the analyte specific fluorescent analyte detection dye. Multiple subpopulations of particles can be used to identify and quantify multi-analytes in a single analytical sample. Near infrared (NIR) fluorescent labels useful in the detection system are also provided.

  • Patent number: 7157234
    Abstract: A microscale binding assay, analyte binding array, and kits are disclosed, which exploit the mass action law to harvest analyte from a liquid sample. This is achieved by fabrication of sorbent zones having up to ten times the binding capacity per unit area generally obtained on polystyrene microtiter plates. The resulting arrays substantially deplete the liquid solution of analyte during incubation. Accordingly, the assays respond to total mass of analyte in the sample, not analyte concentration. This approach, coupled with direct fluorescence detection in the NIR, yields maximal signal intensity and low background for optimal sensitivity.

  • Publication number: 20060079739
    Abstract: A multifunctional portable medical measurement device and the display method thereof are proposed. The multifunctional portable medical measurement device has a first medical measurement unit, a second medical measurement unit, a key unit, a display unit, and a microprocessor. The microprocessor selects either a first measured value or a second measured value for output to the display unit according to the operation of the key unit. When the portable medical measurement device operates in the second measurement mode, a digital display for displaying only a numeral is used to display the second measured value of the second medical measurement unit. When the portable medical measurement device operates in the first measurement mode, a plurality of digital displays for displaying a numeral is combined to display the first measured value of the first medical measurement unit.

  • Publication number: 20060040251
    Abstract: A portable medical measurement device and method are used for biomedical measurements. The medical measurement device comprises a medical measurement unit for analyzing the reaction of a measured target, a signal receiving unit for receiving a measurement signal, a lookup table for storing reference signals and corresponding parameters, and a microprocessor. When making medical measurement, a measured value of the target is analyzed. Next, a measurement signal is received. The lookup table is then used to find out the corresponding parameter of the measurement signal. Finally, the reaction result of the measured value is calculated out by using the corresponding parameter.
