A Comprehensive Review on Chemical Sensors: Materials, Physico-Chemical Properties and Devices

Dear Colleagues,

Air pollution from industry, transport, and agriculture causes significant harm to both the environment and human health. Therefore, efficient gas-sensing technology, necessary in the detection and measurement of pollutant gases, has become a major global challenge that has attracted significant attention in scientific and industrial fields.

Currently, the detection and monitoring of gases using chemical solid-state sensors play an important role in environmental monitoring, personal safety, and industrial processes control.

These sensors offer several advantages such as highly sensitive detection, cost-effective instrumentation, fast read-out, and the possibility of the miniaturization of instruments to develop point-of-care devices and, consequently, in situ analysis. However, these sensors still lack in terms of selectivity, and they have a narrow working range of gas concentration and temperature. To overcome these drawbacks, a new research field has developed focusing on the influence of nanostructuration of the materials on sensing properties of chemical solid-state sensors. In parallel, development efforts in nanoscience and nanotechnology are concentrated on the integration of bottom-up chemical assembly schemes with conventional top-down microelectronic technologies.

This Special Issue aims to provide a comprehensive collection of the current advances, perspectives, and existing challenges relating to solid-state gas sensors based on nanostructured materials, as well as devices associated with sensitive properties. We cordially invite you to submit short communications, full research articles, and review articles to this Special Issue.

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. Chemosensors 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 2700 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.
