A SYSTEM AND METHOD FOR CONTROLLING FLUIDS WITHIN A MICROFLUIDIC DEVICE

摘要

The present invention discloses an apparatus for providing control of fluids using channels and instruments within a disposable microfluidic device. The apparatus is used for a rapid and cost effective diagnostic system for various diseases. The apparatus provides means for generating a working fluid region between a lower section and an upper section of the microfluidic device such that a magnetic fluid slug is retained at centre within the fluid region by a permanent magnet and the magnetic fluid slug can be moved accordingly within the working fluid region by induced electromagnetic forces. Additionally, the apparatus further provides means for positioning a valve between an upper portion and a lower portion of the microfluidic device such that a channel is formed therethrough and the valve can then be deformed by electromagnetic forces in order to provide a cavity channel for controlling fluids within the microfluidic device.
