Title:
DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/191076
Kind Code:
A1
Abstract:
Provided is a detection device with which it is possible to detect oral microbes in a highly accurate manner. This detection device has: a container for accommodating a sample containing contaminants in the oral cavity and composite particles in which a fluorescent labelling substance is bound to oral microbes; a radiation unit for radiating, into the container, excitation light for exciting the fluorescent labelling substance of the composite particles; a light detection unit for detecting light from the container in a state in which the fluorescent labelling substance is excited; and a detection unit for optically detecting the composite particles in the container on the basis of the result of the detection by the light detection unit, the excitation light being light in the wavelength band of 550 nm or above with which excitation of the contaminants is minimized.
