  • Publication number: 20150118688
    Abstract: Provided herein are methods, systems, and devices for detecting and/or identifying one or more specific microorganisms in a culture sample. Indicator particles, such as surface enhanced Raman spectroscopy (SERS)-active nanoparticles, each having associated therewith one or more specific binding members having an affinity for the one or more microorganisms of interest, can form a complex with specific microorganisms in the culture sample. Further, agitating magnetic capture particles also having associated therewith one or more specific binding members having an affinity for the one or more microorganisms of interest can be used to capture the microorganism-indicator particle complex and concentrate the complex in a localized area of an assay vessel for subsequent detection and identification. The complex can be dispersed, pelleted, and redispersed so that the culture sample can be retested a number of times during incubation so as to allow for real-time monitoring of the culture sample.

  • Patent number: 8790598
    Abstract: The present invention provides reaction cells capable of maintaining stable analytical performance by preventing bubble adhesion and reducing sample carryover even if the amount of sample liquid for a single test is further reduced in the future. The invention further provides an automatic analyzer that uses the reaction cells and a method for enhancing the hydrophilicity of the inner surfaces of the reaction cells. According to the invention, a reaction cell has a first electrode inserted thereinto and a second electrode disposed on the bottom side of the reaction cell. A voltage is applied between the first electrode and the second electrode to cause electric discharge between the electrodes. This allows for enhancing only the hydrophilicity of the bottom inner surface and the four bottom corners of the reaction cell to which large bubbles adhere easily.

    Abstract: The present invention provides a method for reducing reagent usage, comprising the steps of providing a retainer, at least one group of loopholes being provided on the sidewalls of the retainer; providing a colorimetric glass, adapted to be inserted into the retainer, for receiving the first reagent to be observed through said loopholes; providing a cap, for capping the colorimetric glass and the retainer into a whole, after the colorimetric glass being inserted into the retainer. The present invention mainly uses a reagent tube with a retainer having a new structure, a colorimetric glass and a cap, storing the first reagent only in the colorimetric glass, and the volume of the colorimetric glass is far less than that of the current reagent tube, thus the usage of the reagents can be reduced effectively.

  • Publication number: 20120052595
    Abstract: A method is taught for the accurate determination of the premature rupture of membranes (PROM), defined as spontaneous rupture of membranes before the onset of uterine contractions. More specifically, a lateral flow assay strip tests for at least two antigens to greatly limit or eliminate the possibility of false negatives. A built in timer in the cassette holding the lateral flow assay further increases the accuracy of the test. A collection buffer vial with self-contained shipping and dropper caps and built in stand is also taught.
