Abstract

A superior biocompatible spherical nucleic acid (SNA) conjugate was fabricated by grafting siRNA onto the surface of a core composed of a spherical DNA nanostucture we have termed a DNA nanoclew (DC). After uptake by cultured cancer cells, these SNA nanoparticles release engrafted siRNAs by cleavage of intracellular Dicer enzyme. Moreover, in vitro expriments display that such SNAs demonstrate potent gene knockdown at both miRNA and protein levels, while with negligible cytotoxicity.
