- Abstract
The sense of it: A new type of rapid, sensitive, and specific photoluminescence (PL) ‐ based assay has been proposed for the detection of phosphate (Pi) based on the competition of oxygen ‐ donor atoms from Pi with those from the carboxylate groups on a graphene ‐ quantum ‐ dot (GQD) surface for Eu3+ ions (see scheme). The graphene ‐ like structures combined with QD ‐ like optical properties suggest the promising nature of the GQDs as versatile tools in the fields of analytical science and biotechnology.
