Scalable Fabrication of Polydopamine Nanotubes Based on Curcumin Crystals

Herein we for the first time demonstrated a scalable and simple fabrication of polydopamine nanotubes by using curcumin crystal as templates. BET surface area of obtained polydopamine nanotubes is 51.9 m<sup>2</sup>/g. Polydopamine nanotubes show great potential as biocompatible porous nanomaterials.
