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.

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.
