Nanostructured Material-Based Gas Sensors

Dear Colleagues,

With this Special Issue, entitled “Nanostructured Material-Based Gas Sensors”, we aim to gather cutting‑edge research at the intersection of nanoscience, materials engineering, and gas‑sensing technology. Driven by global demands for environmental monitoring, industrial safety, public health, and smart detection systems, high‑performance gas sensors have become essential. Nanostructured materials—including metal oxides, carbon nanomaterials, two‑dimensional materials, nanocomposites, and heterostructures—offer exceptional advantages such as a large surface‑to‑volume ratio, tunable electronic properties, high surface reactivity, and designable morphology, enabling significant improvements in sensitivity, selectivity, response/recovery speed, stability, and low‑power operation.

This Special Issue aligns with Chemosensors' scope, which includes advanced materials, sensor science, and applied nanotechnology. We welcome the submission of original research articles, communications, and review papers focused on fundamental mechanisms, material design, synthesis, characterization, device fabrication, and practical applications. Topics of interest include, but are not limited to, the following: controlled synthesis of nanostructured sensing materials; structure–property–performance relationships; surface modification, doping, and heterostructure engineering; room‑temperature and low‑power gas sensors; flexible and wearable sensing devices; sensing mechanism studies; and real‑world applications in environmental monitoring, breath diagnosis, industrial leakage detection, and smart systems.

With the aim of collating high‑quality contributions from scholars across the globe, this Special Issue seeks to highlight recent breakthroughs, address current challenges such as selectivity, stability, and scalability, and promote the translation of nanostructured gas sensors from laboratory research to industrial and societal applications. We invite researchers to submit innovative work that advances both fundamental understanding and practical development, contributing to the sustainable progress of high‑performance gas‑sensing technology.

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 250 words) can be sent to the Editorial Office for assessment.

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-anonymized 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 2000 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.
