Round 1
Reviewer 1 Report
1. What is the importance of sensing 1,5-diaminopentane and not another type of element or gas?
2. Check the grammar. Section 3.3, line 4.
3. Could you calculate the error between the numerical model and the experimental one? If so, it would be convenient to put a small table where the error values are exposed.
4. According to the previous point, it would be good to include some graph of the error, as well as include more graphs in the results obtained.

Dear reviewer,
Thanks for your comments. Here are our replies:
- What is the importance of sensing 1,5-diaminopentane and not another type of element or gas?
The introduction has been modified to show the reason for sensing 1,5-diaminopentane in our study.
- Check the grammar. Section 3.3, line 4
The grammatical error has been rectified.
- Could you calculate the error between the numerical model and the experimental one? If so, it would be convenient to put a small table where the error values are exposed.
The numerical model just and the experimental model has been calculated. 3 results showing resonance frequency for known mass of the binder have been added to Figure 5 in the result section.
- According to the previous point, it would be good to include some graph of the error, as well as include more graphs in the results obtained.
More graphs have been added to the result section.
Reviewer 2 Report
In order to ensure that the paper is of the highest quality, it is recommended that certain topics be clarified and certain improvements be made. These changes could include, but are not limited to, addressing unclear points, providing additional evidence to back up claims, and revising grammar and sentence structure.
2: error: predetermined
4: Euler-Bernoulli
18: low-cost
25: reference for 1,5-diaminopentane(Cadaverine)
26: there is increase??
29: rewrite
44: developed? Uppercase
68: an analytical
72: reference of the BVD model
Equation 19: results into mode coefficients??
whose determinant is ZERO at Resonance frequencies??
The physical meaning of Cm, Rm and Lm should be defined.
166: Some photograph and more details of the cantilever should be introduced.
179: reference of the instrument

Dear reviewer,

These changes could include, but are not limited to, addressing unclear points, providing additional evidence to back up claims, and revising grammar and sentence structure.
The relevant topics have been clarified and improvements to the introduction made. The grammar and sentence structure has also been extensively revised. More results have been included in the result section and references to claims made.
2: error: predetermined
The whole abstract has been revised and improved, and the grammar corrected.
4: Euler-Bernoulli
The error has been corrected.
18: low-cost
The claim has been removed since it is not an objective of our study.
25: reference for 1,5-diaminopentane(Cadaverine)
References about 1,5-diaminopentane have been added.
26: there is increase??
The grammar has been corrected.
29: rewrite
The Introduction has been revised and rewritten.
44: developed? Uppercase
The Introduction has been revised and rewritten.
68: an analytical
The Introduction has been revised and rewritten.
72: reference of the BVD model
Reference to the BVD have been provided.
Equation 19: results into mode coefficients??
The explanation has been corrected.
whose determinant is ZERO at Resonance frequencies??
The explanation has been corrected.
The physical meaning of Cm, Rm and Lm should be defined.
A description of each variable has been provided.
166: Some photograph and more details of the cantilever should be introduced.
Photographs of the cantilever before and after functionalization has been included.
179: reference of the instrument
References to all the instruments used have been provided
188: a brief description of the modal shapes should be introduced
To avoid unnecessary results in the article, these have been omitted, corresponding resonance frequencies are included.
189: obtained
The spelling and grammar have been corrected.
Table 2: more details about the numerical approach with ANSYS should be introduced
A brief account of how ANSYS was used for the NUMERICAL analysis has been included. It has also been emphasized that it was only used to verify the analytical model.
The figure 5 is a measurement or a simulation result?
Figure 5 is a simulation result and has now been clearly explained in the results.
206: response can be…
The Grammar has been corrected.
The description of figure 6 is not correct
The description for Figure 6 has been corrected.
The results presented in figure 6 are obtained with only one measurement??. Have been tried a series of measurement? Any idea about the error or resolution of the measurement? More details should be included regarding this aspect…
More results for 2 more points have been included in the graph. The error between obtained and anticipated readings has also been included.
220: Experimental results??
The paragraph has been corrected.
225: Some details should be added regarding the possible measurement of a gas. In that case is key the addition of the sensor resolution…
There is a subsequent study with the aim of correcting for non-linearities by using a feedback controller. This study will provide more accurate results that we can depend on to give a resolution and a Limit of Detection for our sensor system. We are currently not able to provide a reliable resolution.
Reviewer 3 Report
First of all, it is difficult to find novelty in this paper.
Also, the paper's data is very small, so it seems difficult to be of great help to readers.
Figs. 4 and 5 are too general graphs, and only Fig. 6 is relevant to this study.
I think it is difficult for this paper to be published in this journal.
Author Response
Dear reviewer,
Thanks for your comments. It might be that the structure of the paper did not make it clear enough. We have now modified the structure and hope you can find it relevant.
