Abstract: A system and method for tagging, tracking, locating and identifying people and vehicles transporting people using Perfluorocarbon tracers. An on-going problem faced by military as well as law enforcement personnel is that of friendly fire incidents. To prevent possible friendly-fire incidents, troops would separate the two layers of the uniform patch, thereby releasing a controlled release of the Perfluorocarbon vapors. Other “friendly” troops, equipped with sensors tuned to the specific perfluorocarbon characteristics would thus be able to literally view a plume around the tagged person or object. The system may conversely be used to tag enemies. Formulations of mixed perfluorocarbons may be used to provide coding of emissions.

Abstract: An immunoassay device has a housing defining a first opening for receiving a solution and a second opening through which a liquid sample is deposited, a strip of sorbent material having a test site with immobilized antigen or antibody for the ligand to be tested, and a filter for filtering the sample. The filter is located at the second opening and directly above the test site. The sorbent material defines a horizontal flow path in the housing for the solution from the first opening to the test site. In use, the sample is first applied via the filter to the test site, and then, after the ligand has been captured, a buffer added through the first opening is used to cause a secondary specific binder conjugated to a marker to migrate horizontally by capillary action to the test site where it can bind to the already captured ligand. This immunoassay offer several advantages over the traditional chromatographic immunoassays.

The signal thus is modulated if one or more of the analytes are present in the sample. The amount of the signal is determined and is related to the presence of one or more of the analytes in the sample. The method may be homogeneous or heterogeneous.

In particular, this invention provides methods for synthesizing novel tracers in which a non-controlled substance is both the starting material in tracer synthesis and the binding site on the resulting novel tracer for the antibody, thereby eliminating the necessity of using controlled substances as starting materials.

It was unexpectedly discovered that the novel tracers of the present invention substantially improve the performance of the continuous flow displacement immunoassay as compared with conventionally designed tracers.

Abstract: The caffeine detector uses a paper chromatographic technique to measure the concentration of caffeine in a beverage.
