Advances in Portable Heavy Metal Ion Sensors

Round 1

Reviewer 1 Report

In the present manuscript, authors have reviewed the advances in portable sensors for heavy metal ion detection. The subject is interesting and a comprehensive review of the relevant literature has been covered.   The review paper may be accepted after few minor changes.

 

 1) Word “progress” should be removed from the key words.

2)  Lines 28-30: sentence “Today, an increasing number ……. through the food chain.” is not clear. It needs to be revised.

3) Remove comma after reference 7 in line 32.

4)  A comparison of detection limits of different methods in tabular form should be given.

Reviewer 3 Report

This review summarize some of the recent advances in the field of portable heavy metal ion sensors. In all, the manuscript is well organized, and the information included is well presented. Certain level of revision is still needed.

1. some sentences are too long and hard to get the point, like lines 43-46, please optimize them. 

2. Lines 54-71, are these information from literature or author? If they came from papers, please insert references. 

3. The units used in the manuscript are not uniform, such as line 0–12 ng-mL^-1 in  line 99, ng/mL in lines 177, mmolL^-1 in line 223, also please correct the spell in line 324, should be 10^-6 M instead of 10 M-6.

4. All the advances in the manuscript are reported individually based on detecting methods. Can they be summarized in a table according to method,  metal ions and detection limits? Also, advantages and disadvantages are welcome to add to compare.

5. In the summary, author mentioned the stability needs to be improved, while in the manuscript, the stability issue are not present in detail. 

6. The section on outlook is usually the most valuable in a high-quality review, but I think it is superficial in this perspective. More detailed suggestions are needed.
