It is generally defined as the intolerance of glucose with the onset or initial diagnosis during pregnancy. This illness affects the placenta and poses a threat to the baby as it affects the supply of proper oxygen and nutrients.Purpose: Due to the high percentage of affected pregnant women, it should be mandatory to evaluate glucose levels during pregnancy and there is a need for a continuous monitoring system.Methods: Herein, the investigators modified the interdigitated (di)electrodes (IDE) sensing surface to detect the glucose on covalently immobilized glucose oxidase (GOx) with the graphene. The characterization of graphene and gold nanoparticle (GNP) was performed by high-resolution microscopy.Results: Sensitivity was found to be 0.06 mg/mL and to enhance the detection, GOx was complexed with GNP. GNP-GOx was improved the sensitive detection twofold from 0.06 to 0.03 mg/mL, and it also displayed higher levels of current changes at all the concentrations of glucose that were tested. High-performance of the above IDE sensing system was attested by the specificity, reproducibility and higher sensitivity detections. Further, the linear regression analysis indicated the limit of detection to be between 0.02 and 0.03 mg/mL.Conclusion: This study demonstrated the potential strategy with nanocomposite for diagnosing gestational diabetes mellitus.Keywords: gestational diabetes, glucose oxidase, graphene, interdigitated electrode, gold nanoparticleGe YLakshmipriya TGopinath SCBAnbu PChen YHariri FLi LDove Medical PressarticleGestational diabetesGlucose oxidaseGrapheneInterdigitated Electrodegold-nanoparticleMedicine (General)R5-920ENInternational Journal of Nanomedicine, Vol Volume 14, Pp 7851-7860 (2019)
