Round 1
Reviewer 1 Report
The following comments may help the authors improving the manuscript:
- In the introduction, the authors need to define what electrokinetic flow is, see for example in the introduction of this ref: https://link.springer.com/content/pdf/10.1007/s10404-017-1866-y.pdf (Microfuid Nanofuid (2017) 21:37 DOI 10.1007/s10404-017-1866-y)
- The authors have not in the manuscript described in detail how the microfluidic chips were made. Please elaborate.
- What is the mixing time of this device compared to the other available, for example, the mixer made from fused silica, Micromachines2017, 8(1), 16; https://doi.org/10.3390/mi8010016

Reviewer 2 Report
Dear Authors,
in your manuscript, the following points should be added / changed to further improve it:
- References: Most of them are relatively old, there is only one from 2019, one from 2018, none from 2020. Please check the recent literature. Please correct also the formatting; there is no need for a full stop behind the journal name, but a lot of spaces missing, commas instead of semicola, etc.
- The template is outdated, the footer shows the wrong year.
- The affiliations 2 and 3 are mixed.
- Abstract: What do you mean by "bias to the bottom wall"? What are EOFs?
- line 50-51: according to your formula, the diffusion time scale is not proportional to l, but to l².
- line 92: What is meant with "-5/3 spectrum"?
- line 99: EDL?
- line 138: Which shape did the alternating field have, is it sinus-like or rectangular or ...?
- Fig. 1: Please make (a) etc. a little bit larger, in the moment they are less visible than the numbers in (a).
- For Eq. 4 a reference should be given.
- Generally, what is the difference between velocities given with capital and with small letters?
- In the text, you state that you cannot measure velocities for y < -40 um. Then I would expect to see in Fig. 3 only approx. the upper half ... or symmetric halves, as also mentioned in the text. Why is both not the case here?
