Gold and nickel are the components of nanorods used to separate biomolecules. The rods can act as a high-surface-area scaffolding for biospecific recognition events in a variety of bioseparation schemes. The magnetic Ni block not only provides specificity with respect to His-tagged proteins but also allows one to conveniently remove rods from a solution by using a magnetic field (see scheme).
