  • Patent number: 7867716
    Abstract: The present invention includes an apparatus, system and method for stochastic sensing of an analyte to a protein pore. The protein pore may be an engineer protein pore, such as an ion channel at temperatures above 55° C. and even as high as near 100° C. The analyte may be any reactive analyte, including chemical weapons, environmental toxins and pharmaceuticals. The analyte covalently bonds to the sensor element to produce a detectable electrical current signal. Possible signals include change in electrical current. Detection of the signal allows identification of the analyte and determination of its concentration in a sample solution. Multiple analytes present in the same solution may also be detected.

  • Publication number: 20070298511
    Abstract: The invention relates to a nanopore sensor system including methods of fabrication and uses disclosed herein. In some embodiments, the invention relates to a substrate comprising a lipid membrane, preferably a phospholipid bilayer film, having a nanopore and a gel surrounding said lipid membrane. In additional embodiments, the invention relates to compositions and methods of using and making a substrate that has a lipid membrane having a single channel protein surrounded with a gel. In further embodiments, the invention relates to a method of detecting an analyte by mixing a nanopore sensor with a solution suspected of containing an analyte, measuring electrical properties, and correlating changes of electrical properties to the existence of an analyte.
