  • Patent number: 12390808
    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.

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.

  • Publication number: 20110024024
    Abstract: Provided are apparatuses and methods of making a transfer belt. The method can include providing a hollow mandrel including an interior surface and rotating about a longitudinal axis. The method can also include dispensing a coating liquid through a dispensing tip over the interior surface of the rotating mandrel and using a doctor blade to smooth the coating liquid to form a layer of coating. The method can further include curing the layer of coating to form a seamless belt over the interior surface of the mandrel and releasing the belt from the interior surface of the mandrel, wherein the belt has a thickness uniformity in the range of about 100 nm to about 1 um.
