The handling editor said, either make revisions again, but the page charge will increase to 2700 CHF; or withdraw the submission...

After considering, I decided to withdraw the submission. The academic editor is probably the chairman of this journal. If they don't agree, there is no need to make revisions, wasting everyone's time... Moreover, the guest editor worked hard to bring in submissions, just to have the journal reject them?

I will not actively submit to any MDPI journals in the future, nor will I agree to review articles. It's too ridiculous. I wish the journal the best under the foresight and strict requirements of the academic editor.

To all the teachers and students who work hard on experiments and research, be careful when selecting a journal!

An extremely frustrating submission experience
Received an invitation to contribute as a guest editor for a special issue. The discount for page charges is reduced by 50% when submitting, but the executive editor said three communications were too many and insisted on deleting one, leaving me speechless.
First round of review took 10 days, with three reviewers and suddenly a new academic editor appeared. While the three reviewers all suggested revisions, the academic editor surprisingly rejected the submission, claiming it did not align with the scope of the journal. If it doesn't align, why submit it for review in the first place...
Forgot to mention, during the revisions, only two out of the three reviewers provided feedback, and the revision time was limited to only ten days.
Managed to rush through the revisions, but when uploading, discovered that another reviewer had also provided feedback without any notification of additional reviews. Submitted a request for a two-week extension, but the reviewer added 9 more comments... The executive editor insisted on one week, so had to work overtime to finish.
Moved on to the second round of review, which surprisingly was quite speedy despite the interruption of a national holiday. Received an email after two weeks requesting a payment of 1350CHF for page charges upon acceptance.
And then, the frustrating part - one week after confirmation, the article was still not officially accepted. Sent an inquiry and was informed that only one out of the three reviewers agreed to accept, while the other two did not respond. The academic editor still disagreed and suggested transferring the submission

How long did it take, bro, from applying to acceptance?

Biosensors journal has been upgraded to Q2, indicating great potential for development.

The speed is still very fast~ It is more rigorous than imagined. There were three reviewers, one acceptance, and two minor revisions. The reviewers for the minor revisions all provided sharp opinions and supplemented experiments. The editor is very responsible, but there are too many email reminders! From submission, revision, upload, to payment, all actions, all authors will receive more than a dozen emails! This experience is very unpleasant.

Except for being a third-tier area, everything else is fine.

Excuse me, should I select "topic" or "all" in the submission system? I have chosen a specific relevant topic, but I'm not sure if it will be slower.

From submission to receiving the reviewer's comments, it took a total of 24 days. In the process, one reviewer rejected it because they felt that the direction was not suitable. Another reviewer was then sought, and they requested minor revisions followed by major revisions. After 10 days of major revisions, it was resubmitted, and the minor revisions were provided the same morning. The minor revisions were submitted the same evening, and acceptance was given after 4 days. In total, it took 38 days from submission to acceptance.

I have two invited papers for OA journals (Biosensors and Nanomaterials) and am looking for a partner who can provide publication fees. We can be co-corresponding authors. Interested individuals can contact me at vwznnan@163.com.

Hello, may I ask how to format the references for Biosensors? Is it necessary to add the DOI after the reference and then have it edited? How should it be done?

The submission speed is super fast, feedback is given within a week, modification suggestions are replied within ten days, acceptance is made within two weeks, and publication will be seen within a month. The impact factor is steadily increasing, and we look forward to the continuous improvement of the journal.

One word; fast! The efficiency is very high, and the opinions are also very pertinent.

The journal has just released its impact factor. It is a multidisciplinary journal that includes both review articles and research papers. The reviewers are quite responsible, with three reviewers for the first review. The result was major revision, and they requested a return of the revised manuscript within 10 days. The efficiency is quite high. The second review requires minor revisions, and the authors are given 3 days to make the revisions. Once the revisions are made, the manuscript is accepted. The quality of the journal is good, but the only downside is that there is a fee for publication. This is unavoidable for open-access journals. However, the speed of publication is relatively fast.
