View the Complete Application at the US Patent & Trademark Office
A general methodology for 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 and sensors take advantage of the ability of alkaline phosphatase (ALP) to convert glucose-1-phosphate to glucose, and the ability of PGMs to detect the generated glucose. The disclosed sensors can be part of a lateral flow device. Methods of using such sensors for detecting target agents, for example to diagnose disease, are also provided.
