Potential of volatile organic compounds as markers of

Volatile organic compounds (VOCs) emitted by a human body form a chemical signature capable of providing invaluable information on the physiological status of an individual and, thereby, serving as signs of life for detecting victims after natural or man-made disasters.

Canine scent detection in the diagnosis of lung cancer

Moreover, sniffer dogs have been employed in pre-clinical studies for cancer diagnosis [22, 23]. In 2006, M c C ulloch et al. reported a ivity and specificity of 99% for sniffer dogs to diagnose lung cancer from patients’ breath samples. However, this study might have been biased by odours related to other diseases, therapies and smoking.
