Special Issue Information
Dear Colleagues,
The archetypal chemical sensor is a low-cost, small, and foolproof device that instantaneously provides valuable data about an analyte (i.e., the target compound) in a desired medium. Current efforts of the scientific community aim to get as close as possible to this ideal model by improving materials, transducers, or measurement protocols. In the former case, many different strategies can be adopted to enhance the characteristics of sensing layers, for example by synthesizing completely new materials to improve the intrinsic selectivity and sensitivity; by organizing molecules or building blocks into ordered structures or patterns (e.g., nanostructured material); by combing organic and inorganic materials into hybrid heterojunctions; or by modifying polymer-based materials to tune their reactivity and mechanical resistance. At the same time, advances in electronics allow having miniaturized device that are highly sensitive, cheap, and sometimes flexible or connected to wireless. Thanks to this progress, nowadays smart sensor networks can communicate with each other; large sensor arrays can be allocated in a minimal space; and isolated, dangerous, or poorly-accessible locations can be remotely explored by drones or autonomous vehicles.
At the same time, the search for high performance capability should not divert the attention from the suitability of sensors in real scenarios or applications. From the applicative point of view, sensors can be divided into two main types: selective or broad-selective sensors. The former group of sensors is generally utilized to detect and quantify the concentration of a target analyte in a medium; broad-selective sensors are mainly arranged into arrays to provide qualitative information about complex matrices, usually coming from foods, environment or biological systems.
The aim of this Special Issue is to invite researchers worldwide to share works in the chemical sensing field, stimulating the interdisciplinarity of this research topic. We strive to publish innovative results on several aspects of materials used in various chemical sensor applications. For this purpose, original research articles, review articles, and significant preliminary communications are invited, with particular interest in articles describing current research trends and future perspectives in materials applied for chemical detection.
Potential topics include but are not limited to:
- Synthesis and characterization of sensing materials
- Conducting polymers
- Optical sensors
- Nanostructured materials
- Quantum dots
- Metal oxides sensors
- Graphene based sensors
- Hybrid heterojunctions
- Thermal or optical modulated sensors
- Electrochemical sensors
- Sensors arrays
- Electronic nose
- Electronic tongue

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. Materials 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.
