A new breath analyzer detects trace amounts of elements exhaled by patients with certain diseases, including the acetone on the breath of diabetics and nitric oxide by asthamatics. The low-cost infrared emitter developed by Cambridge CMOS Sensors provides a non-invasive way to detect 35 biomarkers like these, its U.K. developers say. "Testing is easy and painless and can be repeated as often as needed," said professor Florin Udrea, co-founder of CCMOSS, which is a spinoff of the Department of Engineering at Cambridge University in the U.K.
