Technology developed by Patrick McCann, a professor of electrical engineering
at the University of Oklahoma, uses lasers to measure the amount of a
molecule -- carbon disulphide in the case of schizophrenia -- that is
known to be present in the breath of people with that particular disease.
"Every molecule has a unique fingerprint and by using the laser,
we can probe that fingerprint, identify which molecules are there and
how many of them are in that sample," Mr. McCann said.
While a breathalyser diagnostic test already exists for asthma, Mr. McCann,
president and CEO of the machine's commercial developer, Ekips
Technologies, says his invention is superior: It's inexpensive, fast,
easy and non-invasive. The company is first focusing on Asthma and lung
cancer, but then is planning to focus on developing a version of the product
