Abstract
(EN)
Provided is a method of adjusting detection sensitivity in detecting a sample in a channel. A detection method of optically detecting a sample includes: forming a multilayer flow, in which at least one of layers of the multilayer flow contains the sample; introducing light into at least one of layers of the multilayer flow; and detecting a signal generated from the multilayer flow in response to the introduced light, to detect the sample. The sample includes one of a chemical substance, a molecule, a cell, a particle, and a mixture thereof. At least one of fluids included in the multilayer flow has a refractive index different from a refractive index of another one of the fluids.

L'invention concerne un procédé consistant à ajuster une sensibilité de détection lors de la détection d'un échantillon dans un canal. L'invention concerne également un procédé de détection consistant à détecter optiquement un échantillon, qui comprend les opérations consistant à : former un écoulement multicouche, dans lequel au moins l'une des couches de l'écoulement multicouche contient l'échantillon ; introduire de la lumière dans au moins l'une des couches de l'écoulement multicouche ; et détecter un signal généré à partir de l'écoulement multicouche en réponse à la lumière introduite, pour détecter l'échantillon. L'échantillon comprend l'un parmi une substance chimique, une molécule, une cellule, une particule et un mélange de celles-ci. Au moins l'un des fluides compris dans l'écoulement multicouche a un indice de réfraction différent d'un indice de réfraction d'un autre fluide parmi les fluides.
