Special Issue Information

Dear Colleagues,

Graphene-based gas sensors are considered particularly promising for air quality and environmental monitoring, health, safety, and industrial and agricultural process control applications due to the excellent electrical, mechanical, thermal, and optical properties of the material that enable the manufacture of highly sensitive and ultra-low noise gas sensors. As the thinnest material in the world, graphene is suitable for the development of wearable, flexible, and miniaturized gas sensors. A graphene-based gas sensor works by adsorbing gas molecules on the graphene’s surface, which act as donors or acceptors of electrons, and by measuring changes in the electrical conductivity of the material. Many prototypes and fabrication methods have been proposed over the past two decades. The most common working principles include resistive, field effect transistors, quality sensitive, and micro-electro-mechanical systems. By use of various graphene hybrids and derivatives, doping mechanisms, and functional groups, the gas sensor performance can be enhanced compared to pure graphene. However, many of these methods are expensive and not easily scalable to mass production. Accordingly, this Special Issue seeks to showcase research papers and review articles that focus on advances and perspectives in the development and fabrication of simple, reliable, stable, highly sensitive, uniform graphene-based gas sensors, novel designs and methods, key applications, and current approaches to commercialization.

We look forward to receiving your submission.

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. Micromachines 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 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.
