Abstract
A rapid method for the separation of nanoparticles having as few as one ligand attached thereto has been developed. The method relies on the size exclusion separation of a population of nanoparticle-ligand complexes having a narrow uniform size distribution. Ligands are typically biopolymers, functionalized to bind to other nanoparticles for the construction of geometric nanostructures.
