Advance and Application of QCM Sensors

During the last two decades, the number of QCM sensing applications has rapidly increased as a consequence of the high specificity, reliability, cost-effectiveness, convenience and quick response of QCM sensors. These types of sensors are based on the fact that QCM resonance parameters (the series resonance frequency shift, Dfs, and the change in the resistance at this frequency, DRm) reflect the density and viscosity changes in the medium of contact. These sensors can work with complete automation and are ideal for real-time non-invasive monitoring. Consequently, QCM sensors are used in countless applications, such as the detection of contaminants, deposition rate monitoring, detection of vapors, volatile organic compounds, environmental pollutants or biofilm growth monitoring, to name a few.

This Special Issue is dedicated to new advances in QCM sensors, their applications and also to the challenging process of measuring QCM resonance parameters, including accurate electrical circuit models. The Special Issue is also dedicated to improvements in the circuit design and in the formalization of new application fields in the study of system and components reliability.

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.
