These structures can be designed to produce significant enhancements in emission efficiencies and/or absorption cross sections compared to isolated nanocrystals. http://www.lanl.gov/orgs/tt/license/technologies/index.php?fuseaction=home.viewTechnology&id=839 Thu, 6 Aug 2009 00:00:00 -0600 We have developed magnetic beads that carry stabilized carbohydrate ligands that capture influenza. These beads can be dried, reconstituted, are shelf stable and inexpensive. These beads are not only superior in handling over antibody based capture beads, but have been shown to capture influenza virus from cultured samples 8 fold better than the current state of the art antibody. The beads further have low non specific binding avoiding carry over of protease or RNAase activity into assays. The magnetic capturing beads will provide valuable purification and handling of influenza for sequencing, dipstick, protein identification, hemaglutinin precipitation and diagnostic applications that rely on the purity and up - concentration of the influenza virus for detection and identification. http://www.lanl.gov/orgs/tt/license/technologies/index.php?fuseaction=home.viewTechnology&id=1087 Tue, 4 Aug 2009 00:00:00 -0600 In fluorescence-based flow cytometry, sample objects (molecules, cells, microspheres, etc.) are placed in a flowing stream of liquid that carries them through a focused laser beam, where fluorescently labeled targets are detected and analyzed serially (one by one). Throughput is limited by the rate of sample introduction, photon counting statistics, saturation of detection optics, and the overlap of sample objects in the detection volume. To overcome this problem of limited throughput, Los Alamos scientists have developed a scheme, comprising hardware and software, for the parallel analysis of many targets concurrently. http://www.lanl.gov/orgs/tt/license/technologies/index.php?fuseaction=home.viewTechnology&id=105 Wed, 22 Jul 2009 00:00:00 -0600 The LIBS-CS instrument is designed to scan core samples and provide elemental analysis. http://www.lanl.gov/orgs/tt/license/technologies/index.php?fuseaction=home.viewTechnology&id=1018 Thu, 16 Jul 2009 00:00:00 -0600 Methods and apparatus for producing selenium-72, separating it from its daughter isotope arsenic-72, and generating multiple portions of a solution containing arsenic-72 from a reusable parent substance comprised of selenium-72. The invention provides apparatus which can be located at a site where arsenic-72 is used, for purposes such as PET imaging, to produce arsenic-72 as needed, since the half-life of arsenic-72 is very short. http://www.lanl.gov/orgs/tt/license/technologies/index.php?fuseaction=home.viewTechnology&id=21 Tue, 23 Jun 2009 00:00:00 -0600
