... directly above the resonator to indicate the sensing region. To achieve high sensitivity and robust environmental stability for noninvasive glucose detection, this study proposes a novel planar microwave sensor structure. The microwave sensor is based on the principle of loading interdigitated...

... to present a chitosan ( CS )/glucose oxidase (GOx)-graphene oxide ( GO )/screen-printed carbon electrode ( SPCE ) electrochemical biosensor that enables direct electron transfer between GOx and the SPCE, allowing noninvasive glucose detection in complex biological fluids.
