Dear Colleagues,

Molecular sensors have been recognized as smart ‘devices’ capable of solving a variety of problems related to environment and health. With the booming of supramolecular chemistry as a new scientific area, it has enabled us to promote deep insights into the mechanistic understanding of chemical sensors in recent years. Molecular recognition is one of the most important events in biology and an important paradigm in supramolecular sensing. Supramolecular chemistry is the intersection of chemistry, biology, and diagnostics, which is the study of non-covalent bonds between molecules and/or ions. Sensing applications of supramolecular chemistry, in which molecules are chosen for their size, shape, and charge complementarity with the desired analyte, rely on exploiting the forces involved in the formation of non-covalent 'host–guest' complexes. The principles of this chemical sensor design include the separation of analytes, the capture of a specific guest, and the output signal from 'host–guest' complexes. In all cases, the requirements of the sensor are the same: the host must bind to the guest in preference to all competing species, and it must register the binding event in a measurable form.

This Special Issue encourages authors to submit their research and contributions on recent advances in analytical supramolecular chemistry.

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. Sensors 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 2400 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.
