Fluorescence cadmium sulfide nanosensor for selective recognition of chromium ions in aqueous solution at wide pH range

•Luminescent CdS QDs were prepared with naturally occurring biopolymer, pectin.•CdS QDs are stable at wide pH range.•Chromium ions selectively quenched the QDs fluorescence at nanomolar range.•CdS QDs recognizes chromium ions in blood plasma and in real water samples. Chromium is recognized as a ser...
