Scientists Device Breathalyzer That Detects Lung Cancer
An average strand of human hair is about 100,000 nanometres in width.
After "training" the arrays to detect a selection of the cancer-specific VOCs, Haick and his team tested it on both artificial mixtures of biomarkers and real human breath.
The devices were able to "distinguish between the breath of lung cancer patients and healthy controls, without the need for de-humidification or pre-concentration of the lung cancer biomarkers," they concluded.
They also suggested the technique could be extended to other forms of cancer.
"Given the impact of the rising incidence of cancer on health budgets worldwide, the proposed technology will be a significant saving for both private and public health expenditure," they say.
Lung cancer claims some 1.3 million lives worldwide each year, accounting for nearly 18 percent of all deaths from cancer, according to the World Health Organisation.
