This paper presents a new miniature reverse-transcription polymerase chain-reaction (RT-PCR) system integrating a sample pretreatment device for fast nucleic-acid amplification and diagnosis of viruses and bacteria. In the system, a two-way serpentine-shape (s-shape) pneumatic micropump and a magnetic bioseparator were developed for separation and enrichment of viruses and bacteria. This new bioseparator...
The present study reports an integrated microfluidic chip for automatic diagnosis applications. A new "S-shape" micromachine-based pneumatic pump using the concept of the time delay of the compressed air flow is adopted to transport a minute amount of samples/reagents and automate the diagnosis process. While compared to traditional pneumatic micropumps, the new S-shape micropumps provide...
