Dear Colleagues,

Metal-organic frameworks (MOFs) are crystalline porous materials, currently developed and successfully applied in numerous fields, especially in the areas of gas separation, storage, and water and CO₂ capture, since the seminal works of O. Yaghi in 1995. The application of MOFs in analytical chemistry is relatively recent, but it has achieved momentum and is indeed currently a widespread area of research. MOFs are used as extractants in analytical methods, for example, as coatings in solid-phase microextraction, as a powder in dispersive solid-phase extraction, or packed in cartridges or disks in (non-dispersive) solid-phase extraction. They have also proven to be adequate materials as stationary phases in the chromatographic field. Further, these materials can be used as standalones or as part of a composite. Clearly, MOFs constitute a promising material able to revolute the analytical chemistry fields in many aspects, and this Special Issue aims to capture the ongoing research in this area.

We are pleased to invite you to participate in this Special Issue of Nanomaterials dedicated to the analytical applications of metal-organic frameworks. This SI aims to address the use of MOFs is different analytical methodologies, covering the inclusion of MOFs as neat materials or as composites in miniaturized solid-phase extraction, in dispersive miniaturized solid-phase extraction, in on-fiber solid-phase microextraction, in thin-film microextraction, as stationary phases in chromatography, and even when MOFs form part of sensors—in all cases with particular emphasis on the applications to simple and complex matrices for food, environmental or biological analyses.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but not be limited to) the following:

• Analytical chemistry;
• Inorganic chemistry;
• Material science;
• Chemical engineering;
• Environmental analysis;
• Food analysis;
• Bioclinical analysis.

We look forward to receiving your contributions.

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. Nanomaterials is an international peer-reviewed open access semimonthly 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.
