Mucus-penetrating DNA nanoparticles: A novel synthetic strategy was used to achieve a dense PEG coating on the surface of cationic polymer-based DNA nanoparticles. The dense PEG coating (blue in scheme) endows the nanoparticles with a muco-inert surface, which enables their rapid mucus penetration (trajectory indicated by gray line) and provides efficient gene transfer in various cell types.
