Abstract: Systems and methods for the inhibition of galactose oxidase. According to least one embodiment of a stabilizing system of the present disclosure, the system comprises a stabilizing agent useful to completely or substantially prevent degradation or inactivation of a diagnostic marker by galactose oxidase in a body fluid including the diagnostic marker. The stabilizing system also includes a detection agent capable of detecting the diagnostic marker.

Abstract: Device for collection and stabilization of biomarkers in liquid samples. In at least one embodiment of a fluid collection device, the device comprises a housing having a top end, a bottom end, and a tubular compartment therethrough, a swab connected to bottom end of the housing and in fluid communication with the tubular compartment, the swab designed to collect a body fluid, and a stabilizing agent contained within the fluid collection device, the stabilizing agent capable of completely or substantially preventing the degradation or inactivation of a diagnostic agent in a bodily fluid upon receipt of the bodily fluid into the fluid collection device. Optionally, the stabilizing agent may be coupled to the swab, and/or contained within the tubular compartment of the housing.

Abstract: System and methods for the detection of biomarkers. In at least one embodiment of a system for the detection of a diagnostic marker in a body fluid of the present disclosure, the system comprises a diagnostic device comprising a plurality of test wells, wherein each test well is capable of containing at least one detection agent, a detection device capable of interacting with the diagnostic device, wherein the detection device is capable of detecting an interaction between the at least one detection agent and a diagnostic marker in at least one of the plurality of test wells, and a stabilization agent contained within at least one of the plurality of test wells, the stabilization agent capable of completely or substantially preventing the degradation or inactivation of the detection agent or the diagnostic marker.

Abstract: Systems and methods for detecting pregnancy. In at least one embodiment of a system of the present disclosure, the system comprises a stabilizing agent useful to completely or substantially prevent degradation or inactivation of a diagnostic marker for pregnancy in a body fluid comprising the diagnostic marker, and a detection agent capable of detecting the diagnostic agent.

Abstract: A portable authentication device and method of authenticating products or packaging by analyzing key ingredients on products or on product packaging is disclosed. Light-sensitive compounds can be used to identify the product or product packaging. The product or product package may include visible or invisible ink containing a particular light-sensitive compound. The ink may be printed in one or more locations on the product or product packaging to produce an authentication mark, such as a bar code. The device includes an assembly for providing a source of light to irradiate the ink containing the light-sensitive compound on the sample product or product package, an optical detector to detect certain spectral properties emitted or absorbed by the irradiated ink and a controller to determine the authenticity of the sample product or product package by comparing the emitted or absorbed properties to a standard.

Abstract: A method is provided for detecting a tracer in a preparation by precipitating a coloring agent from a sample of the preparation, especially where the coloring agent otherwise interferes with detection of the tracer. A sample of the preparation may be contacted with an effective amount of a precipitating agent to precipitate the coloring agent in the sample, yielding a sample supernatant having a reduced concentration of coloring agent compared to the preparation. Detection of the tracer in the supernatant may produce a result which may be evaluated to assist in quality validation in a process of manufacturing the preparation or authenticating the preparation.

Abstract: A portable product authentication device and method for analyzing key ingredients and the relative amounts of key ingredients in products which in turn enables authentication and monitoring products for authenticity, fraud and quality control is disclosed. Particular light-emissive compounds can be used to identify and quantitate the relative levels of key ingredients in the products. The invention includes a probe assembly for providing a source of light to irradiate a sample product, an optical detector to detect emitted light from the irradiated product and a controller to determine the authenticity or quality of the sample product by comparing the emitted light to a standard. A small sample of the product to be authenticated is tested on site (e.g., at the point of manufacture or at the point of distribution) thereby giving immediate feedback as to its authenticity or quality. The sample, together with the light-emissive compound may be placed on a chip.
