1917 results about "Biowarfare Agents" patented technology

A biological agent—also called bio-agent, biological threat agent, biological warfare agent, biological weapon, or bioweapon—is a bacterium, virus, protozoan, parasite, or fungus that can be used purposefully as a weapon in bioterrorism or biological warfare (BW).

Robust system for screening mail for biological agents

Items of mail are rapidly processed in a mail sampling system to determine if the mail is contaminated with a chemical or biological agent. The mail sampling system maintains a negative pressure in a containment chamber and includes a triggering sampler that makes a threshold determination regarding possible contamination, and a detecting sampler that obtains a sample for more detailed analysis in response to a signal from the triggering sampler. A sample of particulates collected from an item of mail is either removed for analysis or analyzed in the system to identify a contaminating agent. Optionally, the system includes an archiving sampler, which archives samples for subsequent processing and analysis, and a decontamination system, which is activated to decontaminate the mail if needed.

Method for rapid detection and identification of bioagents

Method for detecting and identifying unknown bioagents, including bacteria, viruses and the like, by a combination of nucleic acid amplification and molecular weight determination using primers which hybridize to conserved sequence regions of nucleic acids derived from a bioagent and which bracket variable sequence regions that uniquely identify the bioagent. The result is a “base composition signature” (BCS) which is then matched against a database of base composition signatures, by which the bioagent is identified.

Fluorescent polymer-QTL approach to biosensing

A chemical composition including a moiety comprising a quencher (Q), a tethering element (T), and a ligand (L) that associates with and quenches a fluorescent polymer is disclosed. When an analyte sample is introduced, the ligand (L) binds to a target biological agent if it is present, thereby causing the QTL molecule to separate from the fluorescent polymer resulting in an increase in detected fluorescence. The same chemistry is advantageously employed in a competitive assay. An electric field can also be applied to separate the QTL molecule from the fluorescent polymer. A method for detecting targets for these methods are also disclosed.

System and method for inhibiting the decryption of a nucleic acid probe sequence used for the detection of a specific nucleic acid

InactiveUS20060073487A1Reduce or impede a person's ability to designAvoid identificationSugar derivativesMicrobiological testing/measurementGenetic AnomalyNucleic Acid Probes
Sequence-specific nucleic acid hybridization assays are used for the detection of specific genetic sequences as indicators of genetic anomalies, mutations, and disease propensity. In addition, they are used for the detection of various biological agents and infectious pathogens. Because a complementary probe or nucleic acid sequence is required to detect a sequence of interest in a hybridization-based assay, nucleic acid sequencing techniques can rapidly determine the specific probe sequence being used for detection. This allows reverse engineered assays to be produced rapidly. In addition, it enables the circumvention of hybridization-based assays for biological agent or infectious pathogen detection by providing the information necessary to create or alter nucleic acid sequences to produce false positives or false negatives. The present invention provides methods and compositions for inhibiting the identification of specific detection sequences. More specifically, the invention provides masking sequences that mask the identity of specific detection sequences.

Detection and identification of biological agents using Bragg filters

A method of sensing an environmental agent, comprising obtaining a sample from the environment and transferring the sample into the working fluid for dispensation to a detection module. The sample and working fluid mixture is filtered through a porous polymer Bragg grating. By comparing the refractive index of the grating with the mixture to the refractive index of a grating without the sample, a difference in the refractive index aids in the identification of a hazardous agent in the environment. The sensor also acts as a chemical filter by trapping specific target agents by a highly specific reaction with a conjugate molecule. Recirculation of the working fluid throughout the system provides a sensor that is “always on.”
