ABSTRACT
This study brings out a novel, superselective detection employing thiosalicylic acid-capped ZnS-based quantum dots that display photoluminescence "turn-on" characteristics only in the presence of arsenic in the aquatic medium for the first time. It shows a splendid limit of detection of soluble arsenic down to a few ppb level, much below than the MCL reported value, without being interfered by any other ions.
