... result indicates that field emission properties were not observed on the ZNA at the glucose concentration C500 nM. Conclusions In summary, we demonstrated a new glucose sensor based on the field emitter of ... emission property and conductivity of the ZNA. The ratio of R glucose /R ZnO for the ZNA field emitter -based glucose sensor presents a good dependence on the glucose...
