Special Issue Information
Dear Colleagues,
Photoacoustic spectroscopy is a spectroscopic sensing technique that utilizes the photoacoustic effect to convert the absorption spectrum of a sample into acoustic waves for detection. It is an important branch of spectroscopy used for the analysis and detection of sample composition and concentration. In addition to its high selectivity and sensitivity, comparable to absorption spectroscopy, photoacoustic spectroscopy has several advantages, including signal dependence solely on sample light absorption, immunity to scattered light interference, zero background, signal proportional to light power, and insensitivity of the signal detector to light wavelength. It has found increasing applications in various fields such as environmental monitoring, industrial process control and detection, medical diagnostics, and hazardous defense material detection, showing a rapidly growing trend.
In this Special Issue topic, papers regarding novel research, technology, and, in particular, the advanced methods and novel applications of various sensors are welcomed. Also, advanced sensor algorithms are welcomed. Research and review articles that describe the current state of the art are welcomed. Potential topics include, but are not limited to, the following: cantilever-enhanced photoacoustic spectroscopy, quartz-enhanced photoacoustic spectroscopy, and multiple-sound-source-excitation photoacoustic spectroscopy.

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.
