Abstract: Separation of metal nanoparticles and detection of a gene in a fluid from which the metal nanoparticles are separated are performed in different spaces. A fluid device includes: a gene amplification section that stores a fluid containing metal nanoparticles and that heats the fluid using a photothermal effect of the metal nanoparticles to amplify a gene in the fluid; a metal nanoparticles separating section that separates the metal nanoparticles from the fluid; and a gene detection section that is a space different from the metal nanoparticles separating section and that detects the gene in the fluid from which the metal nanoparticles are separated in the metal nanoparticles separating section.
