Abstract

More than one job: Quantum dots (QDs) conjugated with thiol-modified small interfering RNA (siRNA) were functionalized with thiol-modified RGD and HIV-Tat peptides. These multifunctional QDs were used for the targeted delivery and tracking of siRNA molecules for the knockdown of the EGFRvIII gene, which led to the down-regulation of the PI3K-Akt signaling pathway and the apoptosis of malignant brain cancer cells.
