    CRISPR–Cas9 represents a promising platform for genome editing, yet means for its safe and efficient delivery remain to be fully realized. A novel vehicle that simultaneously delivers the Cas9 protein and single guide RNA (sgRNA) is based on DNA nanoclews, yarn‐like DNA nanoparticles that are synthesized by rolling circle amplification. The biologically inspired vehicles were efficiently loaded with Cas9/sgRNA complexes and delivered the complexes to the nuclei of human cells, thus enabling targeted gene disruption while maintaining cell viability. Editing was most efficient when the DNA nanoclew sequence and the sgRNA guide sequence were partially complementary, offering a design rule for enhancing delivery. Overall, this strategy provides a versatile method that could be adapted for delivering other DNA‐binding proteins or functional nucleic acids. All rolled into one: A biologically inspired delivery vehicle for CRISPR–Cas9 is based on yarn‐like DNA nanoparticles that are synthesized by rolling circle amplification. The DNA nanoclews were efficiently loaded with Cas9 protein/single guide RNA complexes and delivered them into human cells, enabling targeted gene disruption.
