Disk type microfluidic device for conducting immunoassey and biochemistry analysis simultaneously

摘要

A disk-shaped microfluidic apparatus is provided to allow both immune serum test and biochemical test to be carried out simultaneously, thereby reducing the time and effort required for the pathological examination. A disk type microfluidic apparatus(200) comprises a rotatable disk-shaped platform(100); an immune serum test unit which is arranged at the one part of the platform, comprises a plurality of chambers, a plurality of channels connecting the chambers and a plurality of valves controlling the flow of fluid through the channels, and detects the target material from the sample by using a microparticle having a capture probe on surface; and a biochemical test unit(230, 240) which is arranged at the other part of the platform and detects the target material from the sample by the biochemical reaction of the flown sample and the pre-stored reaction solution, wherein the plurality of valves comprises at least one phase transfer valve which comprises a valve material of a heat radiating particle dispersed in a phase transfer material which is solid at a room temperature and is liquid in a high temperature and whose valve material moves in the state molten by the electromagnetic wave irradiated from the external energy source so as to open or close the channels.
