| Outline of Final Research Achievements |
Disease diagnosis based on volatile organic compounds (VOCs) that are excreted from the human body is being realized in recent years. In this study, we report a novel method for analyzing VOCs present in healthy human saliva and urine via thin-film microextraction (TFME) coupled with gas chromatography-mass spectrometry (GC-MS). The VOC extraction was conducted with polydimethylsiloxane (PDMS) films hybridized with ZSM-5 that is one of aluminosilicate zeolites. The saliva and urine samples were collected from 8 healthy volunteers. Approximately 50 to 100 VOCs were obtained from the individual samples, among which 34 and 33 compounds were reproducible for the saliva and the urine samples, respectively. The current study based on TFME using PDMS/ZSM-5 hybrid films would provide a potential methodology for the sensitive analysis of VOCs or new biomarkers present at trace levels in biological samples.
