View the Complete Application at the US Patent & Trademark Office
A methodology for developing highly sensitive and selective sensors that can achieve portable, low-cost and quantitative detection of a broad range of targets using only a personal glucose meter (PGM) is disclosed. The method uses recognition molecules specific for a target agent, enzymes that can convert an enzyme substrate into glucose, and a PGM. Also provided are sensors, which can include a solid support having attached thereto a recognition molecule that permits detection of a target agent, as well as an enzyme that can catalyze the conversion of a substance into glucose, wherein the enzyme is attached directly or indirectly to the recognition molecule, and wherein in the presence of the target agent the enzyme can convert the substance into glucose. The disclosed sensors can be part of a lateral flow device. Methods of using such sensors for detecting target agents are provided.
