Abstract: Gold nanorattle probes are provided that are highly tunable, physiologically stable, and ultra-bright Raman probes for in vitro and in vivo surface-enhanced Raman scattering (SERS) applications. The nanorattles contain an essentially uniform gap between core and shell that is tunable and can range from 2 nm to 10 nm in width. This provides numerous advantages including allowing for increased loading with a variety of dye molecules that exhibit SERS in various spectral regions, including the “tissue optical window” for in vivo studies. In addition, the nanorattle probes provide an internal label when used in diagnostic methods to detect nucleic acids, proteins and other biotargets. The nanorattles have an essentially spherical gold metal nanoparticle core, a porous material of silver metal of an essentially uniform width surrounding the nanoparticle core that is loaded with one or more SERS reporter molecules, and an outer gold metal shell encapsulating the porous material.

Abstract: Disclosed herein are methods and compositions for detection of target small molecules in a mixed sample by performing a competition assay between the target and a surrogate and subsequently detecting the complex types in a nanopore device.
Abstract: In some aspects the invention is directed to methods of analyzing a polynucleotide which include steps of directing to a nanopore an excitation beam having a predetermined polarization state; translocating a polynucleotide through the nanopore, wherein nucleotides of the polynucleotide are labeled with fluorescent labels having absorption dipoles and wherein the nanopore spatially orients the fluorescent labels so that during translocation the adsorption dipoles are substantially unresponsive to the excitation beam; detecting changes in fluorescent signals generated by the fluorescent labels as nucleotides with fluorescent labels exit the nanopore and absorption dipoles thereof become responsive to excitation by the excitation beam with the predetermined polarization state; and identifying nucleotides exiting the nanopore from the changes in fluorescent signals.
Abstract: Disclosed herein is a self-supporting, dissolvable, film containing dexmedetomidine or a pharmaceutically acceptable salt thereof. The film is administered orally to treat various conditions, particularly agitation, by transmucosal delivery of the active agent.

Abstract: Systems, methods and compositions of matter according to the present invention, can be used in capture/enrichment, gene expression profiling and targeted sequencing. Provided are systems, methods and compositions concerning the enhancement of nucleic acid hybridization specificity and controlling the shapes of melting curves revealed by nucleic acid hybrid pairs to optimize nucleic acid analysis. These systems, methods and compositions comprise producing a positively charged surface or surface coating, on the surface of microarray slides or other types of surfaces similarly purposed, which enhances melting curve analysis to the point of allowing detection or differentiation of small changes in sequences between nucleic acid binding partners. The accuracy or resolution of melting curve analysis was to be sufficient to distinguish between the melting of perfect matched dsDNA and dsDNA with the smallest possible change in sequence, a one base pair mismatch.

Abstract: [Problem] If lidocaine is composed of non-aqueous patch, the adhesive power of the preparation tends to get lower, as the composition amount of lidocaine is higher. It is popular to solve lidocaine in dissolving agent in order to compose lidocaine in patch and release effective amount into skin. However, if the amount of dissolving agent gets higher, the adhesive power gets extremely lower, so that an long-time attachment is difficult. [Solution] A non-aqueous patch comprising lidocaine and/or its reactant, and a dissolving agent which are contained in a base of plaster, the plaster being hold by a support, of which strength of 50% stretched to longitudinal direction is less than 2,000 g/50 mm and of biaxially-oriented stretch cloth.

Abstract: A therapeutic composition comprising a purified fraction of adipose-derived mesenchymal stem cells encapsulated in a three-dimensional biocompatible gel matrix, and methods, and systems for preparing and using encapsulated adipose-derived mesenchymal stem cells. Hydrogel microbeads encapsulating stem cells maintain the viability and location of the stem cells for an extended period as compared to stem cells in suspension. The gel matrix allows the release of cellular factors from the encapsulated stem cells to surrounding tissues to achieve desired therapeutic results.
Abstract: A method of marking an inventory item includes providing an activatable smoke generator and a reservoir for holding a smoke fluid and adapted to provide a flow of smoke fluid to the generator. The reservoir contains a smoke fluid including a carrier nucleic acid having a uniquely identifiable sequence, and upon activation of the smoke generator, marker smoke is generated and targeted to flow over the inventory item. The method further includes activating the smoke generator to produce the marker smoke including the carrier nucleic acid so as to cause the marker smoke to flow over the inventory item and thereby to detectably mark the inventory item with carrier nucleic acid. The invention provides methods for stably binding and immobilizing deoxyribonucleic acid onto objects and substrates. The method includes exposing the deoxyribonucleic acid to alkaline conditions, and contacting the deoxyribonucleic acid to the object or substrate.

Abstract: A method includes conveying a detection solution containing a target amplicon into a detection module of a molecular diagnostic test device. The detection module includes a detection surface including a series of capture probes to which a first portion of the target amplicon is bound when the detection solution is conveyed. A first reagent formulated to produce a visible signal indicating a presence of the target amplicon is then conveyed into the detection module. The first reagent is bound to a second portion of the target amplicon when the first reagent is conveyed. A second reagent is conveyed into the detection module. The second reagent includes a precipitating substrate formulated to catalyze the production of the visible signal by producing an insoluble colored product when the second reagent is in contact with the first reagent. The method includes viewing the visible signal via a transparent portion of the detection module.
