2. In the abstract; “consolidated by a spark plasma sintering....” add some quantitative data
3. The abstract should be re-written to summarize the work; the abstract should state briefly the purpose of the research, the principal results and major conclusions.
4. The Introduction should be focused and goes over the topic; what is the gab to cover in this work
5. All abbreviations should be defined in the first place only
6. Page 6, Section 2.2...., should be revised with more details and steps are to be clear

Reviewer 2 Report
The article deals with the preparation and analysis of graphene nanoribbons-hydroxyapatite nanocomposite.
Minor comments to the article:
1) AUthors show the Raman spectrum of nanocomposite. It would be interesting to compare it with the HA spectrum.
2) There typing mistakes in Results section (184 line).
3) How the density presented in Fig. 6 was evaluated?

Done
2) There typing mistakes in Results section (184 line).
Checked
3) How the density presented in Fig. 6 was evaluated?
The results were statistically evaluated by the Kernel Density Estimation method.

Reviewer 3 Report
Paper describes a logical series of experiments and careful analytical characterization studies. The figure resolution is quite low and higher resolution would improve the paper. Images of the CNTs before and after the unzipping process would be good to observe as would higher mag fracture surfaces which showed the GNRs and the fracture mode, but is not essential. The supplier of the CNTs and their physical properties could be helpful for readers.

High quality images will be submitted separately. CNTs information and GNRs results (before and after unzipping) are similar to the reference was used and corrected in the text.
