  • Publication number: 20150065694
    Abstract: Here, we describe a preassembled plasmonic resonance nanocluster. One embodiment is used for microbe detection and typing. The metallic nanoparticle acceptors with microbe surface antigen epitope, and quantum dot (QD) donors with Fab antibody, are assembled into an immuno-mediated 3D-oriented complex with enhanced energy transfer and fluorescence quenching. The coherent plasmonic resonance between the metal and QD nanoparticles is exploited to achieve improved donor-acceptor resonance within the nanocluster, which in the presence of microbial particles is disassembled in a highly specific manner. The nanocluster provides high detection specificity and sensitivity of the microbes, with a sensitivity limit down to 1-100 particles per microliter and to attomolar levels of a surface antigen epitope. A few specific examples of the plasmonic resonance nanocluster used in microbe detection are disclosed along with ways in which the complex can be easily modified for additional microbes.

  • Patent number: 8930645
    Abstract: Methods and apparatus facilitate data streaming in bulk storage devices by generating linked lists containing entries for both user data and metadata. These linked lists containing mixed data types facilitate receiving and outputting user data, and to insert or ignore, respectively, metadata corresponding to that user data without interrupting flow of the user data.

  • Publication number: 20140250273
    Abstract: Memory modules and methods of operating memory modules re-build mapping information from data read from last valid physical pages. Corruption of mapping information is detected. A last valid physical page associated with logical data blocks is read. Mapping information is obtained from the data read from the last valid physical page, and mapping information is re-built using the mapping information obtained from the last valid pages.

  • Publication number: 20140187436
    Abstract: This invention provides a nanoplasmonic molecular ruler, which can perform label-free and real-time monitoring of nucleic acid (e.g., DNA) length changes and perform nucleic acid footprinting. In various embodiments the ruler comprises a nucleic acid attached to a nanoparticle, such that changes in the nucleic acid length are detectable using surface plasmon resonance. The nanoplamonic ruler provides a fast and convenient platform for mapping nucleic acid-protein interactions, for nuclease activity monitoring, and for other footprinting related methods.

  • Patent number: 8732388
    Abstract: Memory modules and methods of operating memory modules embed mapping information within blocks of memory cells to which the mapping information pertains. In particular, when a page is written for a logical data block, that page includes a snapshot of the current mapping information for that logical data block. In this manner, the last valid physical page of a logical data block will contain a physical/logical mapping of that block. Thus, instead of scanning every valid page of the memory device to rebuild the mapping information, the memory module may scan only for the last valid physical page of each logical data block. Once the last valid physical page is discovered for a logical data block, the latest mapping information for that logical data block may be read from that page.

  • Patent number: 8685743
    Abstract: A nanoplasmonic resonator (NPR) comprising a metallic nanodisk with alternating shielding layer(s), having a tagged biomolecule conjugated or tethered to the surface of the nanoplasmonic resonator for highly sensitive measurement of enzymatic activity. NPRs enhance Raman signals in a highly reproducible manner, enabling fast detection of protease and enzyme activity, such as Prostate Specific Antigen (paPSA), in real-time, at picomolar sensitivity levels. Experiments on extracellular fluid (ECF) from paPSA-positive cells demonstrate specific detection in a complex bio-fluid background in real-time single-step detection in very small sample volumes.

  • Patent number: 8404308
    Abstract: An improved process for manufacture of polymer coated composite substrates is described. a coated composite substrate is prepared in the press by applying a layer of a primer coating composition to the surface of a compressible mat comprising fibers and/or particles and a resin binder. The primer coating composition is formulated preferably as a fast setting polymer latex capable of forming a chemically crosslinked polymer matrix when applied to the surface of a compressible mat. a thermosetting top coat composition can be applied directly over the wet primer coating composition before heat-processing the mat to improve surface quality and release characteristics. Compressing and heating the coated mat produces a primed composite substrate directly out of the press.
