Microfluidic device for simultaneously conducting multiple analyses

Abstract

Provided is a rotatable microfluidic device for conducting simultaneously two or more assays. The device includes a platform which can be rotated, a first unit which is disposed at one portion of the platform and detects a target material from a sample using surface on which a capture probe selectively binds to the target material is attached, and a second unit which is disposed at another portion of the platform and detects a target material included in the sample by a different reaction from the reaction conducted in the first unit.

AI Technical Summary

Benefits of technology

The present invention provides a disc-shaped microfluidic device that can simultaneously conduct different assays using a common platform. The device includes a platform that can be rotated, and two units for conducting different assays. The first unit detects a target material using a surface to which a capture probe is attached, and the second unit detects the target material using a reagent that reacts with the target material. The device also includes a microfluidic structure with valves for controlling the flow of fluid through the channels. The valves comprise at least one phase transition valve which can open or close its corresponding channel path using heat. The device can quickly and accurately conduct different pathological tests simultaneously within one device.

Problems solved by technology

Conventional pathological tests require a lot of work and various kinds of equipment.

However, even if clinical pathologists have required skill, it is difficult to perform various kinds of tests at the same time.
