Development of sensitive and selective probes for cupric ions (Cu(2+)) at cell and tissue level is a challenging work for progress in understanding the biological effects of Cu(2+). Here, we report a ratiometric two-photon probe for Cu(2+) based on the organic-inorganic hybrids of graphene quantum dots (GQDs) and Nile Blue dye. Meanwhile, Cu-free derivative of copper-zinc superoxide dismutase (SOD) - E2Zn2SOD is designed as the unique receptor for Cu(2+) and conjugated on the surface of GQDs. Th ...[more]
