Abstract

And then there was one: Anisotropic nanoparticle syntheses often contain impurity nanostructures. Functionalization of the products of such syntheses with DNA (see scheme (1)) allows the relative interaction strengths between particles to be tailored. The desired nanoparticle component can then be crystallized selectively (2) and separated to arrive at samples of significantly improved purity (3).
