People today spend most of their time indoors; many use fragrances in closed restrooms and bathrooms at home public spaces for masking odors. However, volatile organic compounds (VOCs) that are emitted from indoor have been reported recent years to pose a risk health. In this work, microneedle trap samplers (NTSs) were fabricated, packed with sulfonated divinylbenzene (SDVB) adsorbents, used pa...

Ascomata of two truffle species, Tuber borchii and T. asa-foetida, both naturally growing in woodlands of the Basilicata region (southern Italy), were identified on the basis of ascospore morphology and compared under a volatile organic compound profile to determine the particular volatile organic compounds that characterize each taxon. Solid-phase microextraction-gas chromatography-mass spectr...

Bacteria use chemical signals to sense each other and to regulate various physiological functions. Although it is known that some airborne volatile organic compounds function as bacterial signalling molecules, their identities and effects on global gene expression and bacterial physiological processes remain largely unknown. Here we perform microarray analyses of Escherichia coli exposed to vol...
