Abstract

Here, we describe a new approach for preparation of luminescent lanthanide graphene in the presence of dipicolinic acid (DPA). Hg2+ can competitively bind with DPA which greatly quenches the fluorescence and the resultant complex is able to selectively and sensitively detect cysteine with a detection limit of 5 nM.
