Special Issue Information
Dear Colleagues,
Nanoparticles (NPs) are highly effective for selective separation and extraction in various fields due to their unique properties, such as high surface-area-to-volume ratio, tunable size, and functionalizability. The main mechanisms of action include adsorption, where NPs adsorb specific molecules thanks to their functional groups; magnetic separation, which allows the recovery of magnetic nanoparticles (MNPs) with an external magnetic field; and catalytic processes, where NPs facilitate chemical reactions to convert target substances into separable forms. Additionally, membrane technologies with NPs improve selectivity and permeability in the separation of complex mixtures. Applications span environmental remediation, removing heavy metals and pollutants from water and soil; biotechnology and medicine, purifying biomolecules like proteins and DNA; chemical engineering, enhancing separation processes in the petrochemical industry; and the food and agriculture sector, extracting antioxidants and vitamins. NPs offer high efficiency, selectivity, and reusability, but face challenges such as stability, environmental and health risks, and the need for scalable and cost-effective methods. Despite these challenges, nanoparticles represent promising advancements in selective separation and extraction, with ongoing research to enhance their practical applications.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Separations is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
