Special Issue Information
Dear Colleagues,
Exploiting novel gas-sensing materials, optimizing device geometry, adopting suitable fabrication techniques, and developing new gas sensing strategies represent an active area of research towards molecular detection of targeted gases. Recent progress in the synthesis of nanomaterials and the fundamental understanding of their properties has led to significant advances in nanomaterial-based sensors.
For these applications, it is essential to design and synthesize gas-sensing materials with ultrahigh surface-to-volume ratios and modulated surface activities, with enhanced sensitivity, selectivity, and long-term stability (SSS) properties, able to fast respond to different gases. To this extent, current research efforts are directed toward developing high-performance gas sensors with a low operating temperature at low fabrication costs. Nanostructured materials are at the core of the development of any room-temperature-sensing platform.
Inspired by graphene research, two-dimensional (2D) nanosheets and nanocomposites, which have been shown to be alternative substitutes for traditional metal oxides sensors, are attracting increasing interest considering their high surface to volume ratio, wide range of chemical compositions, and their unique thickness-dependent physical and chemical properties.
This Special Issue welcomes the submission of original research papers or comprehensive reviews that demonstrate or summarize significant advances in the synthesis and application of novel materials and functional nanostructures with potential applications in a variety of gas sensing 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. 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 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.
