You can now measure glucose without pain and without drops of blood

This new sensor for measuring blood glucose has been created by researchers from the University Park campus of Penn State University in the United States, doctors Huanyu Cheng, and Dorothy Quiggle led the development and construction of the device that uses laser-induced graphene, This atom-sized material, made up of layers of carbon, after reviews and tests, was built with nickel due to the high sensitivity to glucose, but finally Professor Cheng agreed with gold this in order to reduce the risks potentials of an allergic reaction, the sensor is coin-sized and non-invasive.
