Nona-Arginine Facilitates Delivery of Quantum Dots into Cells via Multiple Pathways

<table>Gel retardation analysis of the interaction between QDs and SR9. QDs were premixed with SR9 at different molecular ratios. Lane 1: QDs without SR9. Lanes 2–5: QDs mixed with SR9 at ratios of 10, 20, 30, and 60, respectively. The decrease in mobility reflected the formation of QD/SR9 complexes.</table>
