Round 1

Reviewer 1 Report

This article reviews nanomaterial-based approaches used for diagnosis of HBV and HCV. The literature cited are latest, but this article should be reconsidered after some issues being addressed.

1. This article reviews many nanomaterial-based methods and states their performance simply, but I think its too simple. The authors should give the advantages and disadvantages, as well as suitable analysis for each method, which are important for supporting the further research.

2. What real applications have been achieved by these methods? What occasions these approaches are suitable for? I think the related information should be indicated.

3. What does the cccDNA mean in the main text. It should be noted.

Reviewer 2 Report

This review reports on the advancement of nanomaterials for the detection of HBV and HCV. Overall, the article structure is reasonable. The types of nanomaterials are rounded. I can recommend it for publication in Molecules after addressing the following questions:

1. The innovation, necessity and feasibility of nanomaterials for HBV and HCV detection should be mentioned in the Introduction.

2. For some examples, relevant curves and figures should be provided, such as the examples in Sections 2.1 and 2.3.

3. The relationship between Section 2.5 and the others should be demonstrated in the Introduction.

4. Have nanomaterials been used practically in medical detection?

5. The limitations and possible solutions of nanomaterials for HBV and HCV detection need to be discussed at the end of Sections 2.1–2.4.

Reviewer 3 Report

This manuscript provides a helpful review of how varied types of nanomaterials have been employed to offer new detection capabilities for the B and C virus forms of hepatitis. After a short Introduction section, the authors present the centerpiece of the review in the form of a table (Table 1). The table contains entries representing nanomaterials-based detection work from 45 references. Sections of the table are divided by materials dimensionality (0, 1, 2) and there is also a category for composite nanomaterials. The sections of the paper are organized along these same divisions and each has text consisting of a running list of very concise descriptions of the referenced work.

In my opinion, the review is generally acceptable since the compilation of referenced work in Table 1 offers sensor researchers a useful resource on published work, particularly as the field will continue to move forward. There are some points on which this review could be made easier to read and more substantial. First, there are a number of grammatical errors throughout the text, and I offer a significant list of suggested and needed modifications below (by line number). I will note too that as a review, it includes only two figures - one a simple introductory schematic for the main materials categories of Table 1, and the other offering some adapted graphics to illustrate several nanocomposite detection examples. In my opinion a more complete review would endeavor to include a somewhat longer Introduction, some overarching conceptual aspects (supported by additional instructive figures) which are critical to the role of nanomaterials in hepatitis sensing, as well as more figures to enrich the 0, 1 and 2 dimensional work included in the review (in the style of the included Figure 2 for nanocomposites).

I consider a substantial majority of my listed wording changes as necessary for making the manuscript more readable. My other suggestions would expand the manuscript in important ways to make it a more impressive “Review”.

Round 2

Reviewer 1 Report

The authors respond all the questions, and the quality of this article has been improved. I aggree its publication after solving the following minor errors.The “figure” in line 193 and line 241 should be corrected as “Figure”. I suggest the authors check the article thoroughly and correct spelling errors carefully.

Reviewer 2 Report

This review has been improved much after revision. I think it can be accepted at current state.
