摘要：

Tip-functionalized nanorods: Single-particle spectroscopy shows that functionalization of small gold nanorods with thiol groups leads to a broadening of the plasmon resonance by chemical interface damping. By specifically functionalizing the tips of the nanorod (see picture) this broadening is nearly eliminated while the sensing performance is maintained relative to fully functionalized particles.
