Topology Determines DNA Origami Diffusion in Intestinal Mucus.

ABSTRACT: Efficient nanomedicine delivery across mucosal barriers remains a challenge due to the complex and poorly understood relationship between nanoparticle design and mucus transport. Here, we present DNA origami as a platform to investigate how the nanoparticle shape and ligand patterning influence diffusivity in mucus. By decoupling these parameters while maintaining identical material composition, we systematically evaluated the diffusion of rod, icosahedral, and rectangular nanostructures by using high-resolution single-particle tracking. Our results reveal that diffusivity in mucus is not solely determined by shape or functionalization alone but by their interplay: while unmodified rods diffused poorly, their mobility increased significantly upon antibody functionalization, reaching a maxi
