What is Red-Emitting Graphene Quantum Dots for Hg(II) Detection about?

This study presents the synthesis of red-fluorescent graphene quantum dots (G-GQD) from guava leaves, which serve as a turn-off probe for the detection of hazardous mercury ions (Hg(II)) in water. The G-GQD exhibits strong fluorescence in the far-red spectral region and demonstrates high selectivity and sensitivity for Hg(II) detection, with a detection limit of 82 mM. The eco-friendly and cost-effective approach highlights the potential of G-GQD for environmental monitoring and sensing applications.
