ナノザイムベースのラテラルフローアッセイおよびデバイス

Resumen de: WO2025041169A1

The present invention provides a kit, a device and an in-vitro assay based on a nanozyme-based lateral flow assay utilizing para-phenylenediamine of optimal concentration 0.1mM to 10mM as a chromogenic substrate for catalytically active aptamer-conjugated gold-nanozyme, which enhances sensitivity. The chromogenic substrate produces a robust brown color upon oxidation by catalytically active nanomaterial. The brown color remains stable for weeks and presents high contrast against the background. This overcomes the limitations of ordinary LFA in detecting analytes present at critical levels that are below microgram per milliliter, often resulting in false negative results. This provides a versatile and high-sensitive point-of-care diagnostic technique for rapid screening of infectious disease antigens and the detection of biomarkers for diseases such as cancer, cardiac and neurodegenerative diseases.
