Noninvasive Electromagnetic Wave Sensing of Glucose
WEBMar 7, 2019 · A mouse blood sample with a glucose concentration from 160 to 310 mg/dL at a step size of 50 mg/dL was tested. An increase in signal attenuation was shown with increasing glucose concentration, which resulted from an osmotic shock of red blood cells (RBCs) that only occurred in vitro.
