Visually colorimetric sensing of hazardous metallic ions based on gold nanoparticles (AuNPs) has been considered a facile, on-site, and reliable monitoring route, yet the improvement of detection limit, as well as environmental pH tolerance, is still needed. Herein, we present an integrated probe de...
