Gold (Au) and palladium (Pd) species have been widely used in synthetic chemistry, biology, and environmental sciences, raising hard-to-ignore health and environment risks due to their potential toxicity. Herein, a novel dual-functional fluorescent probe was rationally designed and developed for simultaneous quantification and visualization of Au3+ and Pd species in the environmental and biological systems. Significant fluorescence enhancement at 484 and 606 nm and color changes were observed upon addition of Au3+ and Pd0 with high sensitivity....
