Disclosed is a method of processing a specimen in which a target component in a specimen is processed using a specimen processing chip provided with a flow-path, the method including: introducing a fluid into a flow-path to form an interface that divides the fluid from a process liquid used for the processing of the target component with a rim of the interface on an inner wall of the flow-path, the process liquid containing particles including the target component; and moving the formed interface along the flow-path with the rim of the interface on the inner wall so as to force out the particles retained in the process liquid by the fluid.

Method of processing specimen and specimen processing apparatus

Disclosed is a sample processing method for processing a target component in a sample by use of a sample processing chip having a storage portion and a droplet forming flow path, the sample processing method including: storing, in the storage portion, a mixture of the target component and a predetermined amount of a diluent for causing the target component to be encapsulated by one molecule or by one particle into a droplet; heating the mixture in the storage portion to cause thermal convection in the storage portion thereby to mix the target component and the diluent together; and in the droplet forming flow path, forming droplets in a dispersion medium, each droplet containing the diluted target component and a reagent that reacts with the target component.

Sample processing method, sample processing chip, and sample processing apparatus

Disclosed is an analyte detection method for detecting an analyte contained in a biological sample, constituted by irradiating a light of a first peak wavelength on a complex containing an analyte and fluorescent substance which gives off light of a second peak wavelength of 450 nm or higher but not exceeding 900 nm when irradiated with light of the first wavelength of 190 nm or higher but not exceeding 350 nm, detecting the light of the second peak wavelength given off by the fluorescent substance when irradiated by light of the first peak wavelength, by a photodetector, wherein the photodetector has a quantum efficiency in the second peak wavelength that is two or more times the quantum efficiency in the first peak wavelength.
