Abstract

A DNA amplification device utilizing a polydimethylsiloxane (PDMS) and silicon substrate coated with spin-on glass (SOG) is provided. This PDMS layer is irreversibly bonded to the SOG layer of the silicon substrate using oxygen plasma. The amplification device is an inexpensive, microfluidic device, which can be utilized as a portable thermo-cycler to perform PCR amplification of DNA in the field.
