Special Issue Information
Particulate matter (PM) and trace gas sensors with the advantages of low cost, high sensitivity, and high selectivity are strongly required in a broad range of applications, from atmospheric monitoring to industrial process control, and from life science research to biomedical application. Photoacoustic spectroscopy (PAS) is recognized as one of the best tools for PM and trace gas sensing, which relies on the detection of acoustic signals resulting from the light absorption of a modulated laser radiation by the target species. Various photoacoustic approaches have been developed using different acoustic transducers, including condenser and electret microphones, quartz tuning fork (QTF), micromachined cantilever, microelectromechanical systems (MEMSs), etc. Different photoacoustic cell structures have been reported for improving photo-acoustic signals and suppressing noise to further enhance the sensor performance. PAS sensors have one unique advantage, which is that their performance is proportional to excitation optical power. Many methods have been investigated to build up high optical power in the PAS cell to improve the sensitivity of PAS gas detection. Therefore, various photoacoustic techniques with different acoustic transducers and PAS cell structures have been reported with ultra-high sensitivity of parts-per-trillion. The purpose of this Special Issue is to concentrate on advanced photoacoustic spectroscopy based on novel acoustic transducers and novel PAS cell structures developed for various applications, including atmospheric monitoring, industrial process control, biomedical application, etc.

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. Atmosphere 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 2000 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.
