Numerous medical tests use bodily fluids to detect disease or otherwise provide information about a health condition. Diabetics, for example, are used to pricking their fingers to test a droplet of blood for glucose levels, while at-home tests for COVID and flu detect viral particles in nasal mucus.
These tests, however, are varying levels of invasive. This can be a real problem when monitoring fragile patients, such as premature infants, who are often subjected to multiple blood draws. Now, researchers are developing a device that can detect biomarkers for health conditions in air, raising the possibility of noninvasive testing.
鈥淭he device itself is versatile,鈥� says Jingcheng Ma, an assistant professor of aerospace and mechanical engineering at Notre Dame Univ. who began developing the device as a postdoctoral scholar at the Univ. of Chicago. Alongside healthcare applications, Ma adds, the research team is testing the device...
