`Sniff-cam` to detect disease
(PHYSorg.com Chemistry)

Having bad breath can mean someone ate a smelly lunch, but it could indicate that the person is sick. Various scent compounds have been linked to illnesses such as diabetes, lung cancer and Parkinson`s disease, leading scientists to develop technology that measures these substances. However, the challenge is creating instrumentation that can detect low, diagnostic levels of these disease biomarkers. Now, scientists report in ACS` Analytical Chemistry a highly sensitive `sniff-cam` that fits the bill.
