Corrigendum to “Electrically responsive ZnO nanotubes for controlled release of biomolecules” [Ceram. Int. 43(Supplement 1) (2017) S802–S806](S0272884217311367)(10.1016/j.ceramint.2017.05.299)

The authors regret that the incorrect figure and explanation text were used in this article. The correct figure and the explanation text are shown below. The explanation text replaces the first paragraph that appeared under Section 3.1. Morphology of FITC-ZTs in the published article. The authors would like to apologise for any inconvenience caused. Fig. 1(a) shows the SEM image of ZnO nanotubes (ZTs) grown on the ITO/PET substrate as treated in an aqueous solution of Zn(NO₃)₂·6H₂O and HMT at 90 °C for 48 h. As can be observed, ZTs present partial-oriented random distribution with an average length of ~3 µm. A well-defined hexagonal shape with a nanotube structure can be identified as illustrated in top-view image of Fig. 1(b) which showed the nanotube with the diameter of approximately ~45 nm. The dark-field TEM image in Fig. 1(c) further demonstrates that the (002) plane of ZTs disappeared.
