• +. Based on the quenching effect, a design for a “turn-off” fluorescent sensor for Cu2+ and Hg2+ detection with detection limits of 187.99 and 82.14 nM, respectively, was developed. Furthermore, the Au-loaded alginate-based fibers outperformed the pristine Ca-ALG fibers in terms of mechanical properties
