I'm struggling to publish my work because I cannot find a good journal with less publication fee as most of the good journals are charging more than $2000. My work is based on colorimetric LAMP assay with a novel fluorescent dye.
International Journal of Molecular Biology charges $ 1540 for a research article. Please refer to the link below.

Do you wish to publish only in open-access journals? These days most journals offer a transformative publishing option, wherein you can choose to publish under a subscription model and you do not have to pay any money.
Elsevier, Springer, Taylor & Francis, Wiley- all these publishers have a hybrid mode of publication and you have to pay only if you choose to publish in an open-access model. These publishers also have a journal suggester/finder page where you just have to put your title, abstract, and keywords and you will be suggested relevant journals. There you can select the journal based on the scope of the journal and opt for the subscription model when submitting, so if in case the paper gets accepted then you don't have to pay at all.
