Nucleic acid nanostructure for delivery of CRISPR/Cas9‐based gene editing system

Abstract

Abstract CRISPR/Cas9 (clustered regularly interspaced short palindromic repeats/CRISPR‐associated protein 9)‐based gene editing system has aroused great interest in many research fields. However, the efficient and safe delivery of this gene editing system into the target tissues and cells remain a major challenge. During the past decades, nucleic acid nanostructures have been widely developed for drug delivery. In this perspective, we will introduce and discuss the recent progress in the design of multifunctional nucleic acid nanostructures, including RCA‐derived DNA, branched DNA, and hybrid DNA, for delivery of the CRISPR/Cas9‐based gene editing system. Furthermore, we prospect the challenges and future opportunities of nucleic acid nanotechnology in the delivery of gene editing systems.
