Smartphone tool can monitor tissue health by reading a natural oxygen-sensitive molecule
Dartmouth researchers have developed a cell phone-based tool that monitors tissue health by using a naturally occurring molecule to measure the oxygen level in cells. The tool could provide a simple and affordable at-home method for detecting disease and making treatment decisions that is superior to current methods, according to a study in Biosensors and Bioelectronics.
