A method of testing for the presence of a preselected target nucleic acid, protein or antigen in a biological sample by exposing nucleic acids, proteins or antigens to a probe having a catalytic element and binding element. The catalytic element catalyses at least one reaction that results in a physical change such that identifiable elements provide an indication of the presence of the target.

A known amount of marker may be added to a pressurized hydrocarbon fluid, or combined with an additive to form a mixture, and the mixture may be added to a pressurized hydrocarbon fluid. An amount of the marker in the hydrocarbon fluid may be determined. An amount of the additive in the hydrocarbon fluid may be determined based on the amount of the marker in the pressurized hydrocarbon fluid. An inline system may be used for detection of a marker in a pressurized hydrocarbon fluid. The system is fixed in a pressurized hydrocarbon fluid supply line such that pressurized hydrocarbon fluid flowing from a first location to a second location in the supply line passes through the detection system. The hydrocarbon fluid may be a liquid or a gas. The markers may include a variety of optical markers, such as fluorescent markers. Detection of the markers may include, for example, fluorescence detection.

Detection of markers in pressurized hydrocarbon fluids

This invention generally relates to a method and apparatus for direct detection of one or more markers in pressurized hydrocarbon fluids. The apparatus includes a vessel () and one or more valves (). The hydrocarbon fluid () may be a liquid or gas. Markers may include a variety of optical markers, such as fluorescent markers. The apparatus may be coupled to a hydrocarbon fluid source (), and the vessel () may be at least partially filled with hydrocarbon fluid from the hydrocarbon fluid source (). A&#x3e; detector () coupled to the vessel () may be used to detect at least one of the markers in the hydrocarbon fluid () while the apparatus is coupled to the hydrocarbon fluid source () and without the addition of reagents. Detection of markers may include, for example, fluorescence detection.

Direct detection of markers in pressurized hydrocarbon fluids

Devices and methods for extraction, identification, authentication, and quantification of one or more covert markers in a material are disclosed. An extraction system includes a first plug flow mixer for mixing a first fluid bearing a marker and transfer agent into a plug flow. The mixing and flowing of the immiscible liquids causes transfer of the marker from the fluid to the transfer agent. A splitter having filters of different surface energies separates the two immiscible liquids, the transfer agent bearing the marker. A second plug flow can be used to transfer the marker to a second transfer agent. The transferred marker is detected to authenticate the original fluid. The marker can be further isolated, activated, or reacted to perform detection, identification or authentication. With the device, a number of independent processing and analytic steps are combined onto a single, portable unit.

Plug flow system for identification and authentication of markers

A method of determining authenticity of an ingestible product purportedly from a batch of saccharide-marked ingestible product is provided. The ingestible product is a food, beverage, or pharmaceutical, for example. The method includes identifying a sample of the ingestible product to be tested; and testing the sample for a marked presence of the saccharide using a saccharide-specific binding protein. The ingestible product is not authentic when the testing demonstrates an unexpected change in the marked presence of the saccharide, and the ingestible product is authentic when the testing demonstrates no unexpected change in the marked presence of the saccharide.

Authentication of ingestible products using saccharides as markers

The present invention relates to an apparatus and methods for the identification or authentication of liquid products by the addition of an anti-Stokes marker. The invention features an apparatus and method for the identification of a liquid, dynamic or static, that includes adding an anti-Stokes luminescent marker compound to the liquid followed by exposing the compound to a light source of a known wavelength or known wavelengths and then detecting one or more shorter wavelength emissions from the marker, where the identity of the liquid is confirmed by the emission wavelength or wavelengths that are detected and quantified. The irradiating source of light includes, but is not limited to, a laser and other conventional light sources.
