The Rise of Polymeric Microneedles: Recent Developments, Advances, Challenges, and Applications with Regard to Transdermal Drug Delivery
Round 1
Reviewer 1 Report
In this review, Gera et al. introduced the polymeric microneedles in the terms of fabrication methods, challenges and applications. The manuscript can be accepted before addressing following issues:
- The authors should give a content of this review to make the review much clearer.
- The authors should indicate how Figure 1 is made (e.g., which keywords are used in exploring the publications) This information should also be included in the figure caption.
- The quality of the figures needs to be improved.
- For section 3.1, the enzyme responsive microneedle should be added and discussed.
- In the applications part, Figures should be added and discussed when give examples.
- More discussion and comparison should be added especially in introducing the fabrication of the microneedle and their application.

Reviewer 2 Report
- I felt this paper is too generic and there is not much information about techniques or different polymers. Everything is very brief. Authors included mathematical modelling, but they didn't discuss it well.
- Line 155 Fig 1 was referred instead of fig 2. Please correct it to fig 2.
- Table 1 the materials are very few and more common. Please try to include more.
- Line 195 It should be epidermal thickness not “long”
- Line 200 Fig 1 was referred again instead of fig 3
- Figures 4 and 5 are not referred in the paper.
- No discussions on different equipment & focused only on droplet- born air blowing.
- Authors also should look for more recent papers and get more relevant information
