Reviewer 1 Report
Comments and Suggestions for AuthorsThe manuscript is written well. However, I have few recommendations to be considered.
- I suggest to modify the title of the review articles. i think no need to mention the year.
- If any software is used for the creation of graphics, provide the name of the software used.
- It is better to include the name of nanoparticles in full - For example, MnO, CrO NPs, GdO and AgNPs etc.
- line 171- Penicillium citrinum and Rhizopus arrhizus - in italics
- line - Proteus mirabilis - italics
- In 'Factors affect the biosynthesis of metallic NPs' - It would be better to mention whether these factors influence biosynthesis of nanoparticles using various methods - plant extract, fungi, algae or bacteria etc. It would be better to mention few studies. It is better to provide examples.
Minor modification required.

Reviewer 2 Report
Comments and Suggestions for AuthorsThe review article presented to me for evaluation is a detailed summary of biogenic methods of obtaining nanometals using green chemistry tools. The authors have made a very exhaustive review of the available data on methods of obtaining nanometals based on plants, an attempt to explain the mechanisms of nanoparticle formation depending on the biogenic factors used (plants, microorganisms, their metabolites), possible applications and the influence of a number of factors on the yield and properties of nanoparticles.
In my opinion, all chapters of the manuscript are arranged logically and correctly and I have no comments on the merits of the work. The only flaw in my opinion is the too laconic description of algae as a raw material for obtaining nanostructures and their characteristics - the authors should either delve deeper into the subject and describe the various nanostructures that can be obtained using algae (including e.g. Au, Pt, Pb, CuO nanoparticles) or remove this chapter.
In addition, the authors should re-read the entire text very carefully and edit it in terms of missing italics for Latin names, superscripts and subscripts, the interchangeable use of "and" and "&", incorrect spaces when quoting, the interchangeable use of short and long dashes, the aesthetics of tables and figures, the interchangeable use of the same names once in uppercase and once in lowercase in the case of secondary compounds from natural extracts.
It is worth emphasizing that despite the fact that the article is multi-authored and the authors come from countries all over the world, the article is a coherent and logical whole, which is not an easy achievement in such a case.

Reviewer 3 Report
Comments and Suggestions for AuthorsOverall, this review is a good concept.
Whether biosynthetic nanoparticles have good stability and consistency needs to be discussed
