Abstract: The present invention includes an assay method for detecting an analyte in a sample. The assay includes a solid surface such as a nitrocellulose membrane. It also includes providing a sample is applied to the solid surface and detecting the presence or absence of the analyte using a fluorescent label from a lanthanide label. The invention also includes a device for detecting the fluorescence in or on an assay test strip. The device includes a housing, a solid surface and an ultraviolet radiation emitting LED.

Abstract: A method and system for treating a water stream which contains Fouling Organics, where the water stream is recovered from an underground hydrocarbon-containing formation during SAGD oil recovery operations conducted on said formation. The method comprises injecting an oxidizing agent, preferably air, into the water stream when first recovered from the underground formation, and using a porous membrane to separate oxidized Fouling Organics and/or filter separable compounds formed due to injection of the oxidizing agent into the water stream, prior to transferring the water stream to a boiler for re-heating the water stream and turning same to steam for re-injection into said formation.

Abstract: A device, method of use and method of manufacturing of said device for detecting an analyte in a biological fluid. The device comprises an immunochromatographic test strip with a raised, arcuate sample receiving zone. The test strip comprises a bibulous strip positioned above the base wherein the bibulous strip defines a developer receiving zone, a sample application zone and an indicator zone and wherein the zones are in capillary contact with each other permitting a developing fluid to wick from the developer receiving zone, through the sample application zone to the indicator zone. Further, a mobilizable detector agent attached to a marker for binding to an analyte of interest in a sample is positioned downstream from the sample application zone and upstream from an immobilized indicator agent, which is attached within the indicator zone.
