Figure 6

Membrane-encapsulated QDs functionalized with DNA-AuNP. QD-DOPC vesicles were incubated with SH-DNA and hybridized with complementary DNA-AuNP, and then imaged using PL microscopy (a, QD), darkfield scattering microscopy (b, AuNP), and then overlaid to show colocalization (c). When this sample was treated with DI water, the QD emission was no longer localized with AuNP darkfield scattering (e–g), indicating dehybridization of double-stranded DNA and disassembly of QD-DNA-AuNP structures. (d) and (h) show the models for assembly and disassembly of QD-DNA-AuNP hybrid structures.
