Published: April 22, 2025

Point-of-care testing (POCT) devices are revolutionizing health monitoring by enabling rapid and accessible outside conventional laboratory environments. However, achieving laboratory-level accuracy in these portable continues to pose a significant challenge. This study introduces e-Patram, an innovative paper-based POCT sensor specifically designed for the precise efficient of dopamine (DA) urine, critical biomarker neurological health. Regular DA is essential identifying fluctuations that may signal neurodegenerative conditions, such as Parkinson's disease, e-Patram aspires facilitate early detection through noninvasive testing. The utilizes electrochemical methods attain high selectivity DA, even presence common interfering substances like ascorbic acid (AA) uric (UA), which often present urine can complicate due close value their redox potential with DA. By overcoming interference challenges modification electrode, provides reliable measurements comparable standard "catecholamine test." Extensive validation human samples confirms device's precision consistency, underscoring its practical tool routine both clinical everyday settings.
