Nanomaterial-Based Chemical Sensors for Environmental and Energy Applications

Dear Colleagues,

In many instances, the use of nanomaterials in chemical sensing has led to improved sensitivity. For instance, nanomaterials such as graphene or graphene oxide can have very large surface areas which can enhance conductivity in electrochemical sensors. On the other hand, distinct nanoparticles or arrays of nanoparticles can have unique optical and surface chemistry properties that can enhance device performance. In some instances, orders of magnitude improvements in sensitivity have been achieved with nanomaterials. However, within the context of chemical sensing, understanding mechanisms that impart sensor selectivity are still relatively unexplored. Furthermore, issues related to robustness that would enable operation outside a laboratory environment still need development. In many studies, these considerations (i.e., selectivity and robustness) are left behind with sensitivity being showcased alone to demonstrate sensing performance. These additional attributes are very important in the context of chemical sensing for environmental monitoring and renewable energy applications.

In this Special Issue, we invite articles that utilize nanomaterials in chemical sensing in a way that can provide new insights that will benefit society, with an emphasis on providing reliable sensing data that can be utilized in the real world to provide data necessary for solving challenges related to energy and the environment.

We look forward to your participation in 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. 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.
