摘要：

In this work, we develop a miniaturized system for DNA extraction and polymerase chain reaction (PCR). DNA is extracted from whole blood sample by using silica coated magnetic beads. Electromagnetic actuation is employed to manipulate the magnetic beads for transporting DNA molecules in fluidic channels. Thermo-pneumatic valves with low temperature elevation are integrated into the microfluidic chip for isolating/releasing fluidic samples and reagents. The size of the system is 72mmx54mmx11mm. The device fully operates with a 12V DC voltage and automatically performs DNA extraction and amplification processes after samples and reagents are loaded.
