TEM images of endocytosis of PQDs and single molecule labeling with PQD-antibody probes in MGC803 cell. (a, c) TEM images of general labeling with PQDs; the red circles enclose PQD granules endocytosed by MGC803 cells. (b, d) Targeted single molecule labeling with synthesized PQD-antibody probes; the blue arrows pointed out the evenly distributed biomolecule probes in the cytoplasm of the MGC803 cell.
