U-M researcher's idea jells into potential new disease-detection method

Researchers at the University of Michigan have developed a new method to detect nitric oxide in exhaled breath, a potential indicator of diseases such as lung cancer and tuberculosis. The technique uses molecular gels that congeal when exposed to nitric oxide and oxygen, allowing for simpler and less subjective detection methods.
