Abstract

By grafting multiple DNA strands onto one terminus of a polyester chain, a DNA-brush block copolymer that can assemble into micelle structure is constructed. These micelle spherical nucleic acids have a density of nucleic acids that is substantively higher than linear DNA block copolymer structures, which makes them effective cellular transfection and intracellular gene regulation agents.
