Dear Colleagues,

Nowadays, global warming, including climate change, has become a serious problem worldwide. One of the causes is environmental pollution. Specifically, air pollution is rapidly increasing due to modernization and urbanization. In this context, pollutant gases emitted from exhausts, e.g., sulfur dioxide (SO₂) and nitrogen oxides (NOx), and greenhouse gases, including carbon dioxide (CO₂), methane (CH₄), and NOx, are the main drivers of global warming. Therefore, the continuous detection and monitoring of such gaseous pollutants are mandatory to prevent global environmental deterioration.

This Special Issue focuses on the synthesis and production of nanostructure-based sensing layers for chemosensor devices, specifically for environmental monitoring. A chemosensor is a type of sensor that can be used to quickly, accurately, precisely, and sensitively identify the environmental status. All these characteristics are very useful in monitoring since it can be carried out in real-time, allowing decisions to be made to propose corrective and preventive solutions to environmental pollution.

This Special Issue of Chemosensors will be dedicated to recent advances in innovative nanomaterial-based chemosensor devices for air quality monitoring.

Full papers, communications, and reviews are welcome. Topics include, but are not limited to, the following:

• Nanomaterials and/or functionalized nanomaterials with enhanced gas sensing properties (e.g., metal oxides, polymers, carbon-based nanomaterials, hybrid organic-inorganic nanocomposites, etc.);
• The synthesis, functionalization, and deposition techniques of nanomaterials as sensing layer;
• The fabrication and development of chemoresistive gas sensor devices based on nanomaterial sensing layer;
• Applications (indoor and outdoor air quality monitoring).

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.
