Abstract: A device for detecting nucleic acids in a biological sample has a sample port, a lysis station and a sample conduit configured to mix a sample and lysis agent to form a sample-lysis mixture, pass the sample-lysis mixture across a solid-state membrane to capture nucleic acids in the biological sample therein, and receive the remainder of the sample-lysis mixture in a waste chamber. The wash station is configured to introduce the wash solution following the sample-lysis mixture, pass the wash solution across the solid-state membrane to purify nucleic acids captured therein, and receive the wash solution from the solid-state membrane in the waste chamber. The elution station is configured to pass the eluent across the solid-state membrane, elute captured nucleic acids from the solid-state membrane, and pass the captured nucleic acids into one or more reaction chambers for amplifying and detecting the captured nucleic acids.

Abstract: A device for amplifying and detecting nucleic acids in a biological sample has a sample port for receiving a biological sample, a solid-state membrane, a sample conduit, a lysis station, a wash station, an elution station, a waste chamber, and a reaction chamber. The sample port, lysis station and sample conduit are configured to mix a sample and lysis agent to form a sample-lysis mixture, pass the mixture across the solid-state membrane to capture nucleic acids in the sample therein, and receive the remainder of the mixture in the waste chamber. The wash station directs a wash solution across the solid-state membrane and into the waste chamber to purify nucleic acids captured in the membrane. The elution station directs an eluent across the membrane, elutes captured nucleic acids from the membrane, and passes the captured nucleic acids into the reaction chamber for amplifying and detecting the captured nucleic acids.
