Device for detecting substance to be measured, and method for detecting substance to be measured

Abstract

An object of a device and a method for detecting a substance to be measured according to an embodiment of the present disclosure is to conveniently detect a biological substance, such as a bacterium or a fungus. The detection device according to an embodiment of the present disclosure includes a container that retains a solution containing a substance to be measured and a magnetic labeling substance that binds specifically to the substance to be measured, a flow generating unit that generates a flow in a first direction at least in the solution, a magnetic field generating unit that generates a magnetic field gradient in the solution, and a detection unit that detects composite particles, based on motion of particles in a predetermined region in the solution, the composite particles including the substance to be measured and the magnetic labeling substance bound together.

Dependencies are inferred from the claim text.
