Figure 8

Real-time confocal microscopy images of HeLa cells transfected with CdSe/ZnSe QD/siRNA complexes. Soon after transfection, the QD/siRNA was observed on the cell membrane. At 5 h, QD/siRNA had migrated into the cell cytoplasm. Green fluorescence represents siRNA and red fluorescence represents QDs.
