A method for efficiently decontaminating surfaces is provided comprising applying an indicator to a surface wherein the indicator provides an observable or machine readable response when a contamination is present on the surface, wherein the response is located relative to a location of the contamination; and decontaminating the location of the contamination, and optionally rechecking the location of the initial contamination post decontamination to ensure that the surface is free of contamination.

Techniques are disclosed for systems and methods to detect radiation accurately, and particularly in a highly radioactive environment. A system includes a detector module for a radiation detector and a parallel signal analyzer configured to receive radiation detection event signals from the detector module and provide a spectroscopy output and a dose rate output. The parallel signal analyzer may be configured to analyze the radiation detection event signals in parallel in first and second analysis channels according to respective first and second measurement times and determine the spectroscopy output and the dose rate output based on radiation detection event energies determined according to the respective first and second measurement times.

The invention provides methods, compositions and kits for segregating a target nucleic acid from a mixed nucleic acid sample. The methods, compositions and kits comprise a non-processive endonuclease (e.g., a restriction enzyme) or an antibody that binds the target nucleic acid (e.g., has methylation specificity). The mixed nucleic acid sample can comprise prokaryotic and eukaryotic nucleic acid and/or nucleic acid from more than one prokaryotic or eukaryotic organisms.

The present invention provides methods for determining the presence of oxidizing salts. According to the current invention, analyte is collected on a swipe and subsequently heated to a temperature sufficient to release a detectible vapor phase component of the oxidizing salt. The vapor phase component passes reacts with a pH sensitive molecule. Reaction of the vapor phase product with the pH sensitive molecule produces a detectible change in response intensity.

Mass separators are provided that can include at least one electrode component having a surface, in one cross section, defining at least two runs associated via at least one rise, the rise being orthogonally related to the runs. Mass selective detectors are provided that can include at least a first pair of opposing electrodes with each of the opposing electrodes having a complimentary surface, in one cross section, defining at least two runs associated via a rise. Methods for optimizing mass separation within a mass selective detector are also provided, including providing mass separation parameters; providing one set electrodes within the separator having a surface operatively aligned within the separator, the surface, in one cross section, defining at least two runs associated via a rise, the rise being orthogonally related to the runs; and modifying one or both of the rise and/or runs to achieve the mass separation parameters.

Analytical instrument inductors are provided that can include bundled wired conductive material about a substrate. Analytical instrument inductors are also provided that can include: a tubular substrate defining a plurality of flanges extending outwardly from a core of the substrate wherein opposing flanges define portions of the core; at least one pair of wires wound about a first portion of the core and between at least two flanges, the pair of wires extending to and wound about a second portion of the core; and wherein the one pair of wires are operatively coupled to an analytical instrument to provide inductance. Methods for preparing an instrument inductor are provided. The methods can include bundling wires about and within multiple exterior openings of a hollow-cored substrate; and connecting each of the bundles across the openings.

Disclosed are compositions that comprise one or more broad-spectrum capture molecules (including, for example, the small, homodimer-forming lectin protein, Griffithsin), or glycoproteins that coat the viral envelope surface in methods for the identification of one or more virus particles in an airborne, aerosol, or aerosolized sample. Also disclosed are methods for the use of such capture agents in the manufacture of diagnostic reagents (as well as kits, devices, and systems comprising them), useful in developing viral detection platforms that are both rapid and facile to perform, yet highly-sophisticated, accurate, and sensitive. Methods are also provided for using these compositions in the identification, molecular capture, characterization, and design of therapeutic regents related thereto for the treatment of one or more symptoms of a viral infection, or a virally-induced disease in mammals and, particularly, in humans.
摘要:
Pharmaceutical formulations that can include at least one genetically modified OPH enzyme are provided. Methods for treating chemical warfare agent exposure are also provided. Modified biomolecules are also provided.
摘要:
The present disclosure provides electron source devices, electron source assemblies, and/or methods for generating electrons. The generated electrons can be used to facilitate spectroscopy, such as mass spectrometry, including mass selection or ion mobility.
