They examined the effects of AA and UA on the measurement of hydrogen peroxide, a reaction product of glucose oxidase. The characteristics of the fabricated biosensor were evaluated using artificial saliva. The developed MG sensor was able to quantify glucose concentrations ranging from 1.75 to 10,000 μmol/L, which includes salivary sugar concentrations of 20 to 200 μmol/L. When measuring saliva samples from healthy subjects, the output corresponding to the concentration was confirmed, indicating the potential for glucose measurement. This MG glucose sensor could offer a useful method for continuous and noninvasive monitoring of saliva glucose to aid in the management of diabetes patients.
