Recombinant protein (EGFP-Protein G)-coated PbS quantum dots for<i>in vitro</i>and<i>in vivo</i>dual fluorescence (visible and second-NIR) imaging of breast tumors

We report a one-step synthetic strategy for the preparation of recombinant protein (EGFP-Protein G)-coated PbS quantum dots for dual (visible and second-NIR) fluorescence imaging of breast tumors at the cellular and whole-body level.
