Cationic coatings can enhance the stability of synthetic DNA objects in low ionic strength environments such as physiological fluids. Here, we used single-particle cryo-electron microscopy (cryo-EM), pseudoatomic model fitting, and single-molecule mass photometry to study oligolysine and polyethylene glycol (PEG)-oligolysine-coated multilayer DNA origami objects. The coatings preserve coarse structural features well on a resolution of multiple nanometers but can also induce deformations such as twisting and bending. Higher-density coatings
