Controllable DNA binding on Nanoparticles
The novel DNA ‘sticky ends’ can form intra-particle loops and hairpins (e.g. schemes II & III), giving more control over the particles’ interactions than conventional sticky ends that can only form inter-particle bridges (scheme Ia). Researchers at New York Univ. have created a method to precisely bind nano- and micrometer-sized particles together into larger-scale structures …
