Heavy Metal Detection
In article number 2201003 by Aristides Bakandritsos, Michal Otyepka, and co‐workers, recyclable fluorescent nanographenes with high‐affinity pockets for toxic metals enable selective and highly effective decontamination of natural water and quality monitoring with sub‐nanomolar sensitivity for lead and cadmium via photoluminescence quenching or optical lateral‐flow sensors.
Access to clean water for drinking, sanitation, and irrigation is a major sustainable development goal of the United Nations. Thus, technologies for cleaning water and quality‐monitoring must become widely accessible and of low‐cost, while being effective, selective, sustainable, and eco‐friendly. To meet this challenge, hetero‐bifunctional nanographene fluorescent beacons with high‐affinity pockets...
