  • Publication number: 20060148028
    Abstract: A method for detecting microorganisms or cells wherein microorganisms or cells contained in a sample are captured on the surface of the adhesive layer of a collection sheet having a substrate layer containing a focusing marker, an adhesive layer having a predetermined thickness and deposited on this substrate layer, the microorganisms or cells are stained by a staining reagent, and after being automatically focused, the light receiving optical system or the collection sheet is moved relatively by a distance equivalent to that obtained by adding the distance from the surface of the substrate layer to the position of the focusing marker to the predetermined thickness of the adhesive layer from the focusing position by this autofocusing reference point, the microorganisms or cells on the adhesive layer are automatically focused, and a light is radiated on the focused adhesive layer to measure the image and detect the microorganisms or cells.

  • Publication number: 20060073470
    Abstract: A method of counting microorganisms or cells in a sample by labeling the microorganisms or cells with a fluorescent labeling reagent, which comprises contacting the sample containing the microorganisms or cells with an adhesive sheet having an adhesive layer laminated on at least one surface of a substrate to capture the sample; before fluorescent-labeling the microorganisms or cells, obtaining a first fluorescent image of the sample; after fluorescent-labeling the microorganisms or the cells, obtaining a second fluorescent image of the sample, and then determining the difference in the number of luminous points between the first and second images, or determining a differential image between the first and second images and determining the number of luminous points in this differential image, or determining the number of luminous points among the luminous points in the second image located outside non-sensitive regions attached to the individual luminous points in the first image.

  • Publication number: 20050208295
    Abstract: The present invention provides an adhesive sheet and a kit for microbial testing, which enable monitoring of the presence of a microorganism and/or the cell count thereof on a solid surface conveniently on a real time basis, and which accommodate to automated focusing during image analysis. The present invention relates to an adhesive sheet for microbial testing having at least a substrate and an adhesive layer, which adhesive layer is compression-bonded to, and peeled from, the surface of a test article to collect microorganisms, and the surface of the adhesive layer is then subjected to image analysis, wherein a marker for focusing the image is provided in the substrate, or in the adhesive layer, or on the surface thereof.

  • Patent number: 6753190
    Abstract: The present invention relates to an immunological detection method capable of performing detection of an analyte in a test sample, and a kit used therefor. There is provided an immunological detection method for detecting an analyte by using a water-absorbent substrate in which a capture region is positioned in a given region on a surface thereof, the capture region being immobilized with a first immunochemical component capable of specifically binding to the analyte, wherein the detection signal is amplified and a kit used therefor.

  • Patent number: 6203900
    Abstract: A pressure sensitive adhesive sheet for the detection of microorganisms, which comprises a laminate of an adhesive layer mainly composed of a water-soluble polymer and a water-permeable membrane which does not allow passage of the microorganisms; a pressure sensitive adhesive sheet for the detection of microorganisms, wherein the surface of the adhesive layer has a contact angle with water of not more than 90°; and a method for detecting a microorganism, which comprises bringing the surface of an adhesive layer of a pressure sensitive adhesive sheet into contact with the surface of a test object, and then bringing the surface of the adhesive layer into contact with water, said adhesive layer or water containing a chromogenic reagent. The use of the laminate makes it possible to leave only stained microorganisms on the water-permeable membrane and to precisely observe the color developed by the microorganisms.

  • Patent number: 5814326
    Abstract: An insect communication disturbing material comprises a covering material and a pheromone component to be included therein, wherein the included pheromone component exudes on the surface of the covering material in such a condition that it can be transferred and adhered to insect pests which contact with the insect communication disturbing material. The material is used in a method for disturbing insect communication which comprises attracting male adult insects to the above-described material, thereby effecting their contact with the insect communication disturbing material and adhesion of the pheromone component to the body of the male adults, and subsequently allowing the contacted males to be free without capturing them.
