Researchers at the University of Florida in the US have developed a non-invasive device to diagnose and provide treatment methods for people suffering from a variety of diseases.

The tiny sensor can be applied to monitor a diabetic’s glucose levels via the patient’s breath and detect possible indicators of breast cancer in saliva.

The sensor is so small that the moisture from one breath is enough to get a pH or glucose concentration reading in under five seconds and can replace the finger prick kit widely used by diabetics.

The sensor uses a semiconductor that amplifies minute signals to readable levels and contradicts long-held assumptions that glucose levels in the breath are too small for accurate assessment.

The sensor can detect pH or alkalinity levels in the breath, helping asthma sufferers better identify and treat asthma attacks and can pick up indicators of breast cancer in saliva and pathogens in water and other substances.
