Special Issue Information
Dear Colleagues,
In recent decades, Surface Acoustic Wave (SAW)-based chemical and biological sensors using various acoustic wave modes have been established as a valuable alternative and complementation to the classical Quartz Crystal Microbalance (QCM) in areas where the QCM does not provide sufficient sensitivity. The heart of these sensors is the functionalizing layer, deposited on their active surface to increase its affinity to the agent of interest and allow efficient interaction of the SAW with this layer for the generation of a strong noise-free sensor signal. The ability of SAW sensors to tolerate a large variety of solid, semisolid and rubbery films of unique sensing properties, as well as their high sensitivity and low detection limit, is the reason for the considerable research interest in the field.
This Special Issue aims to publish a collection of research and featured articles, highlighting recent results in the field of functionalized SAW sensors that might be of interest to researchers and scholars, not only of the sensor community, but also to scientists working in related areas such as medicine, medical diagnostics, microbiology, virology, chemistry, the food and drug industry and other areas that SAW sensor technology finds various applications in. It will focus on thin films, layers and coatings used to functionalize the active sensor area of SAW sensors to make them appropriate for detecting particular chemical and biological agents of interest. These include, but are not limited to, the following:
- Plasma polymer films;
- Organic layers and substances for biosensor applications;
- Aptamers for highly selective sensor applications, including virus detection;
- Molecular imprinting functionalization;
- Graphene films;
- Epitaxially grown films;
- Atomic layer depositions (ALD);
- Mono- and multilayer Langmuir–Blodget films;
- Modified and unmodified functional films;
- Superhydrophobic soot and coatings;
- Other films, layers and coatings appropriate for SAW sensor functionalization.
We aim to provide a forum for papers describing original research on the following concepts:
- Modeling, design, optimization and fabrication of sensor devices using different SAW modes appropriate for thin-film functionalization;
- Thin films, layers and coatings for SAW-sensor functionalization;
- Highly selective sensing layers;
- Theoretical and experimental work aiming to understanding the sensing mechanisms, properties and operation of functionalized SAW-sensor devices;
- Processing techniques for the preparation of functionalized SAW sensors;
- Applications of practical functionalized SAW-sensors

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. Coatings 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.
