Abstract: Synthesis of gold microtubes and nanotubes suspendable in solution is presented. The synthesis is accomplished using an AAO template route, wherein a polymer tube is used as a sacrificial core. The synthesis produces hollow structures that consist of only gold. These nanostructures exhibit two SPR modes, which correspond to both the transverse and longitudinal modes. The mode assignment was confirmed by measuring SPR behavior as both aligned arrays and in solution. The performance of gold nanotubes as refractive index detectors was quantified and determined to be more sensitive than analogous solid nanorods prepared under identical conditions, and are among the most sensitive nanostructured plasmon sensors to date. Due to their intense and sensitive resonances in the NIR spectrum, these solution-suspendable nanoparticles have potential to be used as in vitro or in vivo sensors.
