Special Issue Information
Dear Colleagues,
Over the last decade, worldwide interest in biosensors has continuously grown due to the high performances obtained with the use of specific bioreceptors and their wide range of applications in biomedical and healthcare sectors, environmental monitoring, food industry, and so on.
Nevertheless, several challenges remain for obtaining reliable biosensors, in particular to satisfy the demand for implantable devices for the diagnosis and management of metabolic diseases. More recently, advances in nanomaterial synthesis opened a new era for the development of biosensors with enhanced performances. Nano-biosensors exploit the unique properties of nanomaterials and their high specific surface that enables immobilization of an enhanced number of bioreceptors at reduced volume.
In this context, a promising technology platform for the development of biosensors is based on electro-acoustic transduction obtained by piezoelectric materials. This technology ensures a high sensitivity and fast response time typical of electro-acoustic devices and, at the same time, ensures miniaturization, low cost, and, eventually, CMOS compatibility.
The main objective of this Special Issue is to highlight modeling, simulation, and fabrication technologies of biosensors based on different configurations of electro-acoustic devices (delay-lines, resonators, etc.) and to exploit propagation of different modes (i.e., SAW, BAW, Love, SH-SAW, and Lamb). Topics of interest also include strategies for immobilization processes of bioreceptors, eventually in conjunction with functionalized nanomaterials.
This Special Issue aims to provide original research papers and reviews on the state-of-the-art, present-day progress and perspectives within the topics of interest.

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. Chemosensors 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 2700 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.
