Photoluminescence (PL) emission as a function of the analyte concentration: PL spectra of graphene QD and InP/ZnS QD incorporated MIMO-z (MIMO-zQ and MIMO-zQ’). Also shown are the PL spectra of graphene QD and InP/ZnS QD incorporated NIMO-z (NIMO-zQ and NIMO-zQ’), which represent the absence of imprinted binding sites.
