DNA Molecules Used To Assemble Nanoparticles

...ts, drugs, and contrast agents, and the ability to link them together quickly and easily in many different ways would enable a clinic to offer 25 different "flavors" of dendrimer with only ten synthesis steps, Baker said. Baker foresees a nanoparticle cluster in which a single dendrimer carries three sin...
