Characterization of targeted nanoparticles carrying siRNA expressing DNA nanocassettes. A) Gel electrophoresis analysis of PCR products. The gel picture shows PCR products of Survivin siRNA (750 bp), control siRNA (750 bp), luciferase siRNA (550 bp) and control siRNA (550 bp) expressing DNA cassettes. B) Gel electrophoresis of QD-DNA nanocassettes. Red QD (emission wavelength of 620 nm) and green DNA fluorescent signals were detected on the gel. Left: red QD; Middle: DNA green fluorescence; Right: overlaying QD with DNA–staining image. QDs with DNA nanocassettes showed orange color. C) Nanoparticle size measurements by dynamic light scattering.
