20110041223SPATIALLY RESOLVED QUANTITATIVE MAPPING OF THERMOMECHANICAL PROPERTIES AND PHASE TRANSITION TEMPERATURES USING SCANNING PROBE MICROSCOPY - An approach for the thermomechanical characterization of phase transitions in polymeric materials (polyethyleneterephthalate) by band excitation acoustic force microscopy is developed. This methodology allows the independent measurement of resonance frequency, Q factor, and oscillation amplitude of a tip-surface contact area as a function of tip temperature, from which the thermal evolution of tip-surface spring constant and mechanical dissipation can be extracted. A heating protocol maintained a constant tip-surface contact area and constant contact force, thereby allowing for reproducible measurements and quantitative extraction of material properties including temperature dependence of indentation-based elastic and loss moduli.02-17-2011

20090271246MERCHANT RECOMMENDATION SYSTEM AND METHOD - Automated generation of a merchant recommendation list is disclosed. When a financial processor obtains rich and relevant information related to consumers and merchants, collaborative filtering, profiling, clustering and predictive modeling techniques are combined to provide merchant recommendations to a consumer. The system analyzes consumer attributes which relate to target consumer attributes to create a target consumer cluster, creates associations based upon merchant attributes and the target consumer attributes and provides the feedback based on the associations.10-29-2009

20100035268MATERIALS AND METHODS FOR SINGLE MOLECULE NUCLEIC ACID SEQUENCING - Provided herein are methods and compositions for real time single molecule sequencing of short nucleotide sequences using nucleotide fluorescent semiconductor nanocrystals-conjugated nucleotide primers.02-11-2010
20100255487METHODS AND APPARATUS FOR SINGLE MOLECULE SEQUENCING USING ENERGY TRANSFER DETECTION - Provided herein are systems and methods for nucleotide incorporation reactions. The systems comprise polymerases having altered nucleotide incorporation kinetics and are linked to an energy transfer donor moiety, and nucleotide molecules linked with at least one energy transfer acceptor moiety. The donor and acceptor moieties undergo energy transfer when the polymerase and nucleotide are proximal to each other during nucleotide binding and/or nucleotide incorporation. As the donor and acceptor moieties undergo energy transfer, they generate an energy transfer signal which can be associated with nucleotide binding or incorporation. Detecting a time sequence of the generated signals, or the change in the signals, can be used to determine the order of the incorporated nucleotides, and can therefore be used to deduce the sequence of the target molecule.10-07-2010
20100261185LABELED ENZYME COMPOSITIONS, METHODS AND SYSTEMS - Disclosed herein are conjugates comprising a biomolecule linked to a label that have biological activity and are useful in a wide variety of biological applications. For example, provided herein are labeled polymerase conjugates including a polymerase linked to one or more labels, wherein the conjugate has polymerase activity. Such conjugates can exhibit enhanced biological activity and/or superior detectability as compared to conventional labeled polymerases. Also disclosed herein are improved methods for preparing such conjugates, and methods and systems for using such conjugates in biological applications such as nucleotide incorporation, primer extension and single molecule sequencing.10-14-2010
20100330570NUCLEOTIDE TRANSIENT BINDING FOR SEQUENCING METHODS - Provided herein are compositions and systems for use in polymerase-dependent, nucleotide transient-binding methods. The methods are useful for deducing the sequence of a template nucleic acid molecule and single nucleotide polymorphism (SNP) analyses. The methods rely on the fact that the polymerase transient-binding time for a complementary nucleotide is longer compared to that of a non-complementary nucleotide. The labeled nucleotides transiently-binds the polymerase in a template-dependent manner, but does not incorporate. The methods are conducted under any reaction condition that permits transient binding of a complementary or non-complementary nucleotide to a polymerase, and inhibits nucleotide incorporation.12-30-2010
20110003343CONJUGATES OF BIOMOLECULES TO NANOPARTICLES - Disclosed herein are conjugates comprising a biomolecule linked to a label that have biological activity and are useful in a wide variety of biological applications. For example, provided herein are polymerase-nanoparticle conjugates including a polymerase linked to a nanoparticle, wherein the conjugate has polymerase activity. Such conjugates can exhibit reduced aggregation and improved stochiometries wherein the average biomolecule:nanoparticle ratio approaches or equals 1:1. Also disclosed herein are improved methods for preparing such conjugates, and methods and systems for using such conjugates in biological applications such as nucleotide incorporation, primer extension and single molecule sequencing.01-06-2011
