Self-assembly of CdCO3-dye hybrid nanotubes based on Trypan Blue dye

▶ A simple reflux route of modifying parameters was used to synthesize CdCO3-TB nanotubes successfully. ▶ TB can be used as a template to prepare CdCO3 nanostructures. ▶ By introducing TB as a heterogeneous template of the mineralization system, the structures can be further modified into nanorods and nanotubes.
