Nanoscale Delivery Systems for Nucleic Acid Therapeutics: Principles and Progress

The delivery of nucleic acid drugs faces multiple obstacles and challenges, including in vivo instability, lack of targeting, poor cellular uptake and inefficient endosomal release. Therefore, gene delivery systems need to be designed to overcome these obstacles to achieve efficient in vivo gene delivery. With the fast development of material science and nanotechnology, many nanoscale delivery systems have been designed and developed for targeted gene delivery. This review introduces the obstacles and challenges in gene delivery, as well as rational design principles for and recent progress in nanoscale gene delivery systems.
