N2 - Water-soluble copper nanoparticles stabilized with L-Phenylalanine (L-PCuNPs) were synthesized and characterized for dual sensing of Fe3+ ions and pH levels. These nanoparticles exhibited green fluorescence at 486 nm, which was quenched by Fe3+ ions, resulting in a color shift from colorless to yellow. Additionally, L-PCuNPs showed pH responsiveness, with increased fluorescence intensity as the pH shifted from acidic to basic. Their effectiveness was further validated through analysis of environmental, biological, and food samples, demonstrating their practical utility across diverse real-world applications.
