I need an open access journal in the field of CNTs based biosensor for glucose detection.I need to get fast response or comments from the reviewers of Q1 & Q2 journal before submission of my thesis .
I would recommend MDPI. They have many journals that are all open access. Specifically their biosensor and bioengineering journals. MDPI is one of my favorite open access publishers, both for articles and for publishing in. Additionally there is PLOS One which is open access as well. Finally there is deepdyve. I haven't tried it out yet, but for a relatively cheap price, it will give you access to a lot of journals. Links below. Good Luck!
「Sensors」 published by MDPI may be the best choice for you. Another recommondation is 「Sensors and Materials」, which provides both regular and OA publications.
