Abstract
(EN)
The invention provides a joined body in which a silicone molded body and another silicone molded body are simultaneously and firmly joined at a plurality of contact points therebetween. The invention also provides a joining method therefor, a microfluidic device capable of suppressing the adsorption of a sample in the interior a microchannel even if silicone is used as material, and a production method therefor. Joining is performed by irradiating ionizing radiation onto one or more contact points with which a first molded body or a second molded body make contact. The transmission of the ionizing radiation through the silicone molded body forming the microchannel lowers the gas permeability thereof and allows the silicone molded body to suppress adsorption to the interior thereof.

L'invention concerne un corps assemblé dans lequel un corps moulé en silicone et un autre corps moulé en silicone sont simultanément et fermement assemblés à une pluralité de points de contact entre eux. L'invention porte également un procédé d'assemblage associé, un dispositif microfluidique capable de supprimer l'adsorption d'un échantillon à l'intérieur d'un microcanal même si du silicone est utilisé comme matériau, et un procédé de production associé. L'assemblage est réalisé en irradiant des rayonnements ionisants sur un ou plusieurs points de contact avec lesquels un premier corps moulé ou un second corps moulé entre en contact. La transmission du rayonnement ionisant à travers le corps moulé en silicone formant le microcanal réduit la perméabilité aux gaz de celui-ci et permet au corps moulé en silicone de supprimer l'adsorption à l'intérieur de celui-ci.

シリコーンの成形体と他のシリコーンの成形体間の複数の接触点で、シリコーンの成形体間を同時に強固に接合する接合体とその接合方法と、シリコーンを素材として用いても、マイクロ流路内の試料の収着を抑制できるマイクロ流体デバイスとその製造方法を提供する。第1成形体又は第2成形体が接触する1又は2以上の接触点に電離放射線を照射し、接合する。マイクロ流路を形成するシリコーンの成形体は、電離放射線が透過することにより、ガス透過性が低下し、シリコーンの成形体内への収着を抑制できる。
