scientists from pennsylvania state university have developed a sensor that can detect signs of diabetes within minutes. however, the most interesting thing is that it uses breath as a marker.
the research team led by professor fan yu has developed a sensor that can detect the concentration of acetone in breath, an important biomarker. unlike sweat sensors that require physical activity, this new device is much simpler. all you need to do is breathe into a bag, insert the sensor, and wait for the results. this prototype is based on laser-induced graphene (a porous material made using a carbon dioxide laser) and zinc oxide. by combining these two materials, a compound is created that selectively captures acetone molecules.
in the future, this technology may not only help with the rapid diagnosis of diabetes, but also track changes in the body caused by diet and exercise.
