Publication number: 20230390764Abstract: The present disclosure provides a microchannel device that has a channel sandwiched between channel walls formed in an inside of a porous substrate, wherein the channel wall contains a thermoplastic resin and a colorant, and wherein an abundance ratio of the colorant is higher in the porous substrate surface area of the channel wall than in an internal area of the channel wall. In the configuration of the present disclosure, since more of the colorant exist on the surface side of the porous substrate in the channel wall, the visibility of the channel is increased, and in addition, since the amount of the colorant in the internal portion of the channel wall is small, the elution of the ions contained in the colorant into the specimen is suppressed, and the measurement accuracy is increased.Type: ApplicationFiled: August 22, 2023Publication date: December 7, 2023Inventors: MAKOTO FUKATSU, MASANORI TANAKA, TAKESHI YAMAMOTO, Keiji Miyazaki, JUN MIURA, HARUNOBU MAEDA, FUKA ENOKIDO, AKIHISA MATSUKAWA, YUHEI TERUI
