There are disclosed compositions and methods to render nucleic acids resistant to nuclease digestion while maintaining sequence selective hybridization competency. The approach relies on utilizing nucleic acids as the polar head group of a nucleic acid-polymer amphiphile in order to assemble well-defined, discrete micellar nanoparticles. Dense packing of nucleic acid in the micelle corona allows for hybridization of complementary oligonucleotides while prohibiting enzymatic degradation.

we report the preparation of paclitaxel-terminated peptide brush polymers wherein cell uptake and toxicity are tunablebased on peptidesequence. Synthesis was enabled using a new paclitaxel-containing chain termination agent for ring-opening metathesis polymerization (ROMP). Critically, reverse phase HPLC could be used to efficiently separate peptide brush polymers consisting of one fluorophore and

While most approaches to nucleicacid delivery rely on secondary carriers and complex multicomponent charge-neutralizing formulations, we demonstrate efficient delivery using a simple locked nucleicacid (LNA)-polymer conjugate that assembles into spherical micellar nanoparticles displaying a dense shell of nucleicacid at the surface. Cellularuptake of soft LNA nanoparticles occurs rapidly within minutes
