Special Issue Information

Dear Colleagues,

A variety of sensing tools are playing increasingly important roles in many applications, making data collection more feasible and easier, even in unusual places. Nowadays, several sensor technologies are rapidly being developed and improved, and at the same time they are becoming less expensive, smaller, and easily portable. In this way, optical sensors demonstrate great potential for the future. Though there are several kinds of sensors available on the commercial market to detect the presence of gases (namely toxic gases, combustible gases, and VOCs) or even gas mixtures, optical gas sensors are rapidly becoming the best method for their monitoring.

Most rely on a change in the effective refractive index and present several advantages, among them: cost-effectiveness, small sample volume usage, simple remote sensing without relying on local power requirements, high flexibility, low propagating loss, immunity to electromagnetic interference and the capacity for multiplexing designs that enable distributed sensor configurations. Besides atmospheric and environment pollution control, there are several industries that have recognized the potential of this type of sensor, including the energy, transport, and construction sectors, but also the food, chemical and medical industries.

This upcoming Special Issue invites you to submit your manuscripts (short communications, original research experimental and theoretical papers, and review articles) regarding advances in the fundamental research and development of optical sensors for the detection of gases, including new sensor platforms and configurations, sensing mechanisms and innovative applications. These contributions may focus on, but are not limited to, the following topics:

  • New optical sensors for gas sensing based on colorimetry, fluorescence, metal–organic frameworks, surface plasmon resonance, spectroscopy, remote sensors, or optical fiber sensors.
  • Applications of gas sensors in food, environmental, biological, and general chemical analyses.
  • Microstructured optical fibers in gas sensing.
  • New sensing materials for optical fiber functionalization in gas detection.

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.
