Figure 8. EM showing CL4–QD delivery with or without peptide to the cytosol of hippocampal neurons.

(A–C) CL4 QD conjugated to the Palm1 peptide is delivered intracellularly and largely dispersed throughout the cytosol (Black dots). (D,E) CL4 QD without peptide is delivered to the cell but largely remains sequestered around intracellular organelles. (F) Negative control. Arrows point to QDs. Scale bars are 200 nm.
