| Abstract | Direct delivery of exogenous non-coding nucleic acids into living cells has attracted intense interest in biological applications. However, the cell entry efficiency and target capture ability remain to be improved. Herein, we report a method for compartmenting the nucleic acids on the surface of poly-adenine-based spherical nucleic acids (polyA-SNAs) for efficient capture of oncogenic microRNAs (miRNAs) in living cells. We find that polyA-SNAs exhibit high cell entry efficiency, which is insensitive to the configuration of the anti-miRNA sequences. By programming the length of polyAs, we precisely engineered the spatial configuration of the anti-miRNA sequences in polyA-SNAs. Compartmentalized polyA-SNAs bind to miRNAs with improved capture ability as compared to densely compacted SNAs. We further demonstrate that polyA-SNAs serve as high-efficacy miRNA sponges for capturing oncogenic miRNAs both in living cells and in mice. The efficient inhibition of miRNAs results in significant suppression of tumor growth. |
