Special Issue Information
Dear Colleagues,
Over the last decade, breath analysis has emerged as a non-invasive and powerful tool for monitoring metabolic changes and environmental exposures.
Metabolites present in exhaled breath provide crucial insights into physiological and pathological conditions, with promising applications in disease diagnosis, treatment monitoring, and personalized medicine. Exhaled breath volatiles and condensate are commonly sampled and analyzed by a range of techniques including mass spectrometry, ion mobility, optical spectroscopy, and electronic sensors.
This Special Issue focuses on novel and cutting-edge approaches applied to the identification, quantification, and interpretation of breath metabolites, particularly addressing challenges such as long-term sample storage and breath-to-breath reproducibility. We especially welcome studies that employ novel informatic workflows, including models which integrate metabolites with respiratory ventilation, machine learning methods for biomarker validation, and multi-omics approaches to determine metabolite sources.
By bringing together innovative research in breath metabolomics, this Special Issue aims to advance the field and facilitate its translation into clinical and environmental health applications.

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. Metabolites 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.
