Smartphone-Integrated Fluorometric Sensor for Phosphate Detection in Eutrophic Water
Abstract: Monitoring inorganic phosphate (Pi) is essential for reducing environmental impact and ensuring ecosystem sustainability. Existing detection methods share several common shortcomings including the necessity for costly laboratory instruments and trained experts, time-intensive procedures, intricate synthesis of multiple reagents, and the limited shelf life of these reagents. To address these limitations, we present an innovative, portable fluorometric sensor for Pi detection that integrates cutting edge technologies: 3D printing, smartphone imaging, and precise fluorophore design. This sensor exhibits remarkable sensitivity across Pi concentration ranges of 0.0031–0.6194 ppm (P) and 0.6194–1.2388 ppm (P), with a low limit of detection (LOD) of 1.27 ppb (P). Moreover, this system shows superior selectivity for Pi over 17 other potentially competitive species and maintains a long shelf life. This cost-effective device has been successfully applied to monitor Pi in lake water samples, showcasing its practical effectiveness. By introducing this novel technology, we aim to develop Pi detection, paving the way for sustainable water resource management and enhanced environmental conservation.
