A Hair-Sized Lung Probe
August 20, 2019 | Terry Sharrer
In an extremely fine optical fiber, Scottish scientists devised a tool for assessing lung disease deep in the organ. “We demonstrated the phenomenon that high-density deposition of carboxyfluorescein covalently coupled to silica microspheres shows an inverse shift in fluorescence in response to varying pH. This platform delivered fast and accurate measurements (±0.02 pH units and ±0.6 mg/L of oxygen), near instantaneous response time and a flexible architecture for addition of multiple sensors “ MORE
